Enum SelectionMode

#[non_exhaustive]
pub enum SelectionMode {
    None,
    Single,
    Browse,
    Multiple,
}

Used to control what selections users are allowed to make.

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 selection is possible.

Single

Zero or one element may be selected.

Browse

Exactly one element is selected. In some circumstances, such as initially or during a search operation, it’s possible for no element to be selected with Browse. What is really enforced is that the user can’t deselect a currently selected element except by selecting another element.

Multiple

Any number of elements may be selected. The Ctrl key may be used to enlarge the selection, and Shift key to select between the focus and the child pointed to. Some widgets may also allow Click-drag to select a range of elements.

fn clone(&self) -> SelectionMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionMode

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

Formats the value using the given formatter.

impl From<SelectionMode> for Value

fn from(v: SelectionMode) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for SelectionMode

type Checker = GenericValueTypeChecker<SelectionMode>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for SelectionMode

type ParamSpec = ParamSpecEnum

type SetValue = SelectionMode

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SelectionMode

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 SelectionMode

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for SelectionMode

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 SelectionMode

type Type = SelectionMode

Type to get the Type from.

impl Copy for SelectionMode

impl Eq for SelectionMode

impl StructuralPartialEq for SelectionMode
