Enum Overline

#[non_exhaustive]
pub enum Overline {
    None,
    Single,
}

Available on crate feature v1_46 only.

The Overline enumeration is used to specify whether text should be overlined, and if so, the type of line.

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

no overline should be drawn

Single

Draw a single line above the ink extents of the text being underlined.

Trait Implementations

impl Clone for Overline

fn clone(&self) -> Overline

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Overline

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

Formats the value using the given formatter.

impl From<Overline> for Value

fn from(v: Overline) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for Overline

type Checker = GenericValueTypeChecker<Overline>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for Overline

type ParamSpec = ParamSpecEnum

type SetValue = Overline

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Overline

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 Overline

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for Overline

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 Overline

type Type = Overline

Type to get the Type from.

impl Copy for Overline

impl Eq for Overline

impl StructuralPartialEq for Overline
