Enum gdk4::GLError

#[non_exhaustive]
pub enum GLError {
    NotAvailable,
    UnsupportedFormat,
    UnsupportedProfile,
    CompilationFailed,
    LinkFailed,
    // some variants omitted
}

Error enumeration for GLContext.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotAvailable

OpenGL support is not available

UnsupportedFormat

The requested visual format is not supported

UnsupportedProfile

The requested profile is not supported

CompilationFailed

The shader compilation failed

LinkFailed

The shader linking failed
