Trait Implementations

impl Clone for FontWidth

fn clone(&self) -> FontWidth

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for FontWidth

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

impl<'de> Deserialize<'de> for FontWidth

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontWidth

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

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

Tests greater than (for self and other) and is used by the > operator.

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