Where can I find string implementation?

[Nan Xiao]

Hi all,

From this post, I can see the string implementation is in https://golang.org/src/runtime/runtime.h previously:  

    struct String

    {

        byte*   str;

        int32   len;

    };

But now, https://golang.org/src/runtime/runtime.h has gone. I try to grep "string struct" in the golang source code,

but can't find string definition.

Where can I find string implementation now? Thanks in advance!

Best Regards

Go has been re-written in Go starting with 1.5, so to say, in order to
build Go >= 1.5 from sources you now need to have Go 1.4 or higher
installed and working.

Consequently, string manipulation has been re-written in Go as well
and hence there's no more C's header files for that.

I'd say the file you need is {src}/runtime/string.go assuming the {src}
is the directory with the Go's source code.
