Enum cogl::GLES2ContextError

#[non_exhaustive]
pub enum GLES2ContextError {
    Unsupported,
    Driver,
    // some variants omitted
}

Error codes that relate to the cogl_gles2_context api.

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.

Unsupported

Creating GLES2 contexts isn’t supported. Applications should use cogl_has_feature to check for the FeatureID::OglFeatureIdGles2Context.

Driver

An underlying driver error occured.
