Enum pango::WrapMode

#[non_exhaustive]
pub enum WrapMode {
    Word,
    Char,
    WordChar,
}

WrapMode describes how to wrap the lines of a Layout to the desired width.

For @PANGO_WRAP_WORD, Pango uses break opportunities that are determined by the Unicode line breaking algorithm. For @PANGO_WRAP_CHAR, Pango allows breaking at grapheme boundaries that are determined by the Unicode text segmentation algorithm.

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.

Word

wrap lines at word boundaries.

Char

wrap lines at character boundaries.

WordChar

wrap lines at word boundaries, but fall back to character boundaries if there is not enough space for a full word.

Trait Implementations

fn clone(&self) -> WrapMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrapMode

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

Formats the value using the given formatter.

impl From<WrapMode> for Value

fn from(v: WrapMode) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for WrapMode

type Checker = GenericValueTypeChecker<WrapMode>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for WrapMode

type ParamSpec = ParamSpecEnum

type SetValue = WrapMode

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for WrapMode

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 WrapMode

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

fn eq(&self, other: &WrapMode) -> 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 WrapMode

fn partial_cmp(&self, other: &WrapMode) -> 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 WrapMode

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for WrapMode

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 WrapMode

type Type = WrapMode

Type to get the Type from.

impl Copy for WrapMode
