These are the possible line break classifications.

Since new Unicode versions may add new types here, applications should be ready to handle unknown values. They may be regarded as Unknown.

Trait Implementations

impl Clone for UnicodeBreakType

fn clone(&self) -> UnicodeBreakType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnicodeBreakType

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

Formats the value using the given formatter.

impl From<UnicodeBreakType> for Value

fn from(v: UnicodeBreakType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for UnicodeBreakType

type Checker = GenericValueTypeChecker<UnicodeBreakType>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for UnicodeBreakType

type ParamSpec = ParamSpecEnum

type SetValue = UnicodeBreakType

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for UnicodeBreakType

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 UnicodeBreakType

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

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