Trait Implementations

impl Clone for FeatureLevel

fn clone(&self) -> FeatureLevel

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FeatureLevel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<FeatureLevel> for c_uint

fn from(value: FeatureLevel) -> Self

impl From<u32> for FeatureLevel

fn from(value: c_uint) -> Self

Converts to this type from the input type.

impl Hash for FeatureLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

fn eq(&self, other: &FeatureLevel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
