Formats the value using the given formatter.

impl Default for FontStretch

fn default() -> FontStretch

Returns the “default value” for a type.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<FontStretch, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FontStretch> for FontStretch

fn from(stretch: FontStretch) -> FontStretch

Converts to this type from the input type.

impl FromValue for FontStretch

fn from_value(value: Value) -> Result<FontStretch, HintedString>

Try to cast the value into an instance of Self.

impl Hash for FontStretch

fn hash<__H>(&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,

impl IntoValue for FontStretch

fn into_value(self) -> Value

Cast this type into a value.

impl Ord for FontStretch

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for FontStretch

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

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Tests less than or equal to (for self and other) and is used by the <= operator.

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

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