Trait luminance::backend::query::Query

pub unsafe trait Query {
    fn backend_author(&self) -> Result<String, QueryError>;
    fn backend_name(&self) -> Result<String, QueryError>;
    fn backend_version(&self) -> Result<String, QueryError>;
    fn backend_shading_lang_version(&self) -> Result<String, QueryError>;
    fn max_texture_array_elements(&self) -> Result<usize, QueryError>;
}

Backends that support querying.

Required methods

fn backend_author(&self) -> Result<String, QueryError>

The implementation author, most of the time referred to as “vendor” or “compagny” responsible for the driver the implementation uses.

fn backend_name(&self) -> Result<String, QueryError>

The backend name.

fn backend_version(&self) -> Result<String, QueryError>

The backend version.

fn backend_shading_lang_version(&self) -> Result<String, QueryError>

The shading language version.

fn max_texture_array_elements(&self) -> Result<usize, QueryError>

The maximum number of elements a texture array can hold.
