Enum gtk4::DeleteType

#[non_exhaustive]
pub enum DeleteType {
    Chars,
    WordEnds,
    Words,
    DisplayLines,
    DisplayLineEnds,
    ParagraphEnds,
    Paragraphs,
    Whitespace,
}

Passed to various keybinding signals for deleting text.

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.

Chars

Delete characters.

WordEnds

Delete only the portion of the word to the left/right of cursor if we’re in the middle of a word.

Words

Delete words.

DisplayLines

Delete display-lines. Display-lines refers to the visible lines, with respect to the current line breaks. As opposed to paragraphs, which are defined by line breaks in the input.

DisplayLineEnds

Delete only the portion of the display-line to the left/right of cursor.

ParagraphEnds

Delete to the end of the paragraph. Like C-k in Emacs (or its reverse).

Paragraphs

Delete entire line. Like C-k in pico.

Whitespace

Delete only whitespace. Like M-\ in Emacs.

Trait Implementations

impl Clone for DeleteType

fn clone(&self) -> DeleteType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeleteType

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

Formats the value using the given formatter.

impl From<DeleteType> for Value

fn from(v: DeleteType) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for DeleteType

type Checker = GenericValueTypeChecker<DeleteType>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for DeleteType

type ParamSpec = ParamSpecEnum

type SetValue = DeleteType

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for DeleteType

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 DeleteType

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for DeleteType

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 DeleteType

type Type = DeleteType

Type to get the Type from.

impl Copy for DeleteType

impl Eq for DeleteType

impl StructuralPartialEq for DeleteType
