Formats the value using the given formatter.

impl Default for FontStretch

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FontStretch

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Ord for FontStretch

fn cmp(&self, other: &FontStretch) -> Ordering

This method returns an Ordering between self and other.
