What `gl::GetUniformLocation` excepts (rust)

[stalker57241]

I'm writing app with rust and opengl, done much work with matrices, but it isn't works. After some tests, I found, that location is -1. but shader's code contains used name. It isn't work when name is &str and used as name.as_ptr().cast() for casting to *const i8 type.

Where is readable docs? May anyone tell me?

Strings without length in the API like glGetUniformLocation need to be 0-terminated, in Rust you could/should use CString
