unwrap() takes self which means it wants to move/consume it, but you have only a borrow of the Option field. as_ref() gives you an owned Option that has a ref to the value inside, and you can unwrap that.
Ok. I see that I only have a borrow of the option field (the &self in the signature of cnt). I do not see why unwrap needs to take ownership. On the LHS c is immutable so why does it not do a immutable borrow? What prevents it doing that? What is the reason for it?
I am happy, I learnt of Option::as_ref and I see what it does, unwrap returns what ever is in the option transferring ownership. Which is OK with a immutable reference but not a value. But I am unhappy because I do not see why.

c is &Option. The signature of unwrap takes self, as mentioned. The dot operator, such as when calling a method, automatically dereferences through the reference. So you end up trying to consume/move a borrowed Option.
No! Routines like unwrap() or expect() only panic if its value is not whatthe caller expected. If the value is always what the caller expects, then itfollows that unwrap() and expect() will never result in a panic. If a panicdoes occur, then this generally corresponds to a violation of the expectationsof the programmer. In other words, a runtime invariant was broken and it ledto a bug.
Basically, at a certain point, writing the same expect() message over andover again for the same common operations becomes a tedious exercise. Instead,good judgment should be employed to determine whether to use unwrap() orexpect() in any given situation.
One common argument against the idea of using good judgment is that it canbe nice to remove human judgment from the equation. If one lints againstunwrap(), then one forces every programmer to write something other thanunwrap(). The thinking goes that if one forces this step, then programmersmight think more deeply about whether their code can panic or not than theywould otherwise. Needing to write expect() and come up with a message, Iagree, exercises more brain cells and probably does result in folks thinkingmore deeply about whether a panic can occur.
I've just finished going through the rust book, and I have one question about it - when should I be using an unwrap/expect, or when should I specifically break it down with a match statement on a Result? I'm under the impression any unwraps should usually be eventually replaced, but are there times where it just doesn't matter and an unwrap is fine?
Rust's preferred manner of handling errors is to propagate them where possible, which is done with ?. Having to write out the longer .unwrap() is a good thing, in my opinion, as it shows a potential panic if you're wrong.
That's based on assumption that .unwrap() is somehow a flaw in the design that needs tidying up. That's not the case: .unwrap() was designed to be obnoxious on purpose, because you shouldn't use it in production code. Instead you should properly handle the errors via error propagation (?), explicit pattern matching, or error combinators.
EDIT: But I do not agree with adding a shorthand for unwrap(). It is good to have to write it (or expect()) out. While I'm fine writing unwrap()/expect(), I also wouldn't want to make it too easy or ergonomic to use. It is certainly something to use with caution.
Even so we have ! fixed for macros, it is still possible to use it for unwrap with a little more burden. The trick is that macros ! must be following an identifier, making it possible to enable writing (exp)! for exp.unwrap(), as well as variable.foo()! etc.
I have a long numpy array with wind direction records, and I'm trying to use numpy's unwrap before running an algorithm to detect jumps in the data. The data contains NaNs, and numpy seems unable to process this. As soon as one NaN is encountered, all following data points returned by unwrap are also converted to NaNs. Is there a way around this?
Yep, select all edges of a cube, mark seam, unwrap then choose unwrap->reset. All faces now share the same UV space. Pretty sure it should work on a larger thing. providing each face is bound by seams.
As mentioned by Miss_B, You unwrap each object individually. I do not quite see why you would even want to try to do lots or all at once. Different items might need different projections. Odds are they all want different textures too anyway.
In Viva, is there a function available to unwrap a waveform by defining its wrap-over value. For eg: please see the below plot. I want to generate lower plot from the upper plot. There are phaseDegunwrap and phaseRadunwrap, they don't serve this purpose.
I am a little confused about which plot you are trying to create - the upper plot from the lower plot or the lower plot from the upper plot? From your description of your question, "to unwrap a waveform by defining its wrap-over value", I think you want to create the upper plot from the lower plot (i.e., unwrap a waveform with some modulus).
Note that it's possible to manually customize panic with expect,but unwrap otherwise leaves us with a less meaningful output than explicithandling. In the following example, explicit handling yields a morecontrolled result while retaining the option to panic if desired.
Hi, I think too that 200000poly for unwrapping is maybe to much.
ps: Instead of using decimation master -wich is a great tool btw-,
I would suggest you to try to use zremesher. I think it gives you lot of control for
amazing efficient results (you can choose by advance, a target number of polygones, etc).
Then, you can have a low poly base that can be unwrapped without any problem into uvmaster.
The unwrapped meshes don't show up in the object browser, but I found another solution. I can just import the solid mesh, generate face groups, and then unwrap. It's still baffling why it doesn't show up though.. One factor that seems to affect the results is whether I use Ascii or binary format for my STLs.
The mistake in the regex come from forum parser. I had troubles with escaping special characters here.
It had to be non greedy
`.W=(?P.?),`
Any way the unexpected unwrap went away but I got something new. No matter I use your or mine syntax.
OK I am home sick with COVID, and feel like I am losing my mind. I have been working on Pothead for about 3 weeks now. I FINALLY got to the UV Unwrap and realized I had one seam wrong. So I selected the seam and unmarked it, but it stayed on the grid. So I selected all the seams and unwrapped them. Then selected the entire pot and selected Reset.
That is when everything broke. Of course I have saved it right as everything fell apart and not a clean UV free version.
Now when I try to make any seam and unwrap it literally blows up. Now I have spent hours randomly clicking on things and it is only getting worse. Here are 3 consecutive pictures. Me clearing the seams. Unwrapping. Putting in a new seam and EXPLOSION.
At the top is the link to my file. I really don't want to start over on this one. Is there a way to go in and delete any UV stuff from the file?
The data-sly-unwrap attribute in HTL is used to remove the wrapping element when including a resource using data-sly-resource. In your case, it seems that the data-sly-unwrap attribute is not working as expected.
Yes, wrapped stETH gets staking rewards at the same rate as regular stETH. When you keep your stETH in a wrapper you cannot see your daily staking rewards. However, when you unwrap your wstETH your new stETH balance will have increased relative to pre-wrapped amount to reflect your received rewards.
This data recipe assumes that you have already generated your interferogram using the Sentinel-1 Toolbox as shown in the image below and would like to follow the unwrapping process. Note that the last step should be Phase Filtering; the product should not be Geocoded (Terrain Corrected) before unwrapping.
Note: Execution time depends on the size of the interferogram. Unwrapping can use a lot of memory. If the unwrapping fails due to insufficient memory, you may wish to create a subset of your area of interest and try again. You may also be able to increase the size of your Virtual Machine.
At this point, you may view your Unwrapped Phase product. However, you will notice that areas of no-elevation incorrectly appear as having data in the Unwrapped Phase image. To fix this, we will terrain-correct and geocode the unwrapped data.
With unwrapping I mean generating the uv coordinates of my extruded shape to put a texture on it. I forgot to mention that I use ExtrudeShapeCustom to make use of the scaleFunction. The playground I mentioned above just shows a simple example but usually the shape has some beveled edges and corners. Since I have to use the scaleFunction of ExtrudeShapeCustom I cannot use CreateBox or ExtrudePolygon.
3.1 Seams If the geometry is a sphere (closed geometry) or in some instances a cylinder (a surface with holes) UV unwrapping will require you to set one or more seams. This is where Add Seam comes into play.
Add Seam: This enables you to, in the preview, select where you want to have a seam. The seam will be highlighted in red. Enable Use as Direction Guide if you want the U direction of the UV-coordinates to follow the seam. When this is enabled, this type of seam will be highlighted in orange.
