Enum TextTransform

#[non_exhaustive]
pub enum TextTransform {
    None,
    Lowercase,
    Uppercase,
    Capitalize,
}

Available on crate feature v1_50 only.

An enumeration that affects how Pango treats characters during shaping.

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 text unchanged

Lowercase

Display letters and numbers as lowercase

Uppercase

Display letters and numbers as uppercase

Capitalize

Display the first character of a word in titlecase

Trait Implementations

impl Clone for TextTransform

fn clone(&self) -> TextTransform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextTransform

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

Formats the value using the given formatter.

impl From<TextTransform> for Value

fn from(v: TextTransform) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for TextTransform

type Checker = GenericValueTypeChecker<TextTransform>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for TextTransform

type ParamSpec = ParamSpecEnum

type SetValue = TextTransform

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for TextTransform

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 TextTransform

fn cmp(&self, other: &TextTransform) -> 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,

Restrict a value to a certain interval.

impl PartialEq for TextTransform

fn eq(&self, other: &TextTransform) -> 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.

impl PartialOrd for TextTransform

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

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

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

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

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

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.

impl StaticType for TextTransform

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for TextTransform

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for TextTransform

type Type = TextTransform

Type to get the Type from.

impl Copy for TextTransform

impl Eq for TextTransform

impl StructuralPartialEq for TextTransform
