Enum pango::FontScale

#[non_exhaustive]
pub enum FontScale {
    None,
    Superscript,
    Subscript,
    SmallCaps,
}

Available on crate feature v1_50 only.

An enumeration that affects font sizes for superscript and subscript positioning and for (emulated) Small Caps.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

Leave the font size unchanged

Superscript

Change the font to a size suitable for superscripts

Subscript

Change the font to a size suitable for subscripts

SmallCaps

Change the font to a size suitable for Small Caps

Trait Implementations

impl Clone for FontScale

fn clone(&self) -> FontScale

Returns a copy of the value.

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

Performs copy-assignment from source.

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

Formats the value using the given formatter.

impl Display for FontScale

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

Formats the value using the given formatter.

impl From<FontScale> for Value

fn from(v: FontScale) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for FontScale

type Checker = GenericValueTypeChecker<FontScale>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for FontScale

type ParamSpec = ParamSpecEnum

type SetValue = FontScale

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: FontScale) -> ParamSpecEnumBuilder<'_, FontScale>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FontScale

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.

impl Ord for FontScale

fn cmp(&self, other: &FontScale) -> 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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for FontScale

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for FontScale

fn partial_cmp(&self, other: &FontScale) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for FontScale

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for FontScale

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifer of self.

impl ValueType for FontScale

type Type = FontScale

Type to get the Type from.

impl Copy for FontScale
