Struct MultiSelectFlags 

pub struct MultiSelectFlags(/* private fields */);

Flags controlling multi-selection behavior.

These mirror Dear ImGui’s ImGuiMultiSelectFlags and control how selection works (single vs multi, box-select, keyboard shortcuts, etc).

Implementations

impl MultiSelectFlags

pub const NONE: Self

Disable Ctrl+A “select all” shortcut.

pub const NO_RANGE_SELECT: Self

Disable range selection (Shift+click / Shift+arrow).

pub const NO_AUTO_SELECT: Self

Disable automatic selection of newly focused items.

pub const NO_AUTO_CLEAR: Self

Disable automatic clearing of selection when focus moves within the scope.

pub const NO_AUTO_CLEAR_ON_RESELECT: Self

pub const BOX_SELECT_1D: Self

Enable 1D box-select (same x, full-width rows).

pub const BOX_SELECT_2D: Self

Enable 2D box-select (arbitrary item layout).

pub const BOX_SELECT_NO_SCROLL: Self

Disable drag-scrolling when box-selecting near edges of the scope.

pub const CLEAR_ON_ESCAPE: Self

impl MultiSelectFlags

pub const fn empty() -> Self

Get a flags value with all bits unset.

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: i32) -> Self

pub const fn from_bits_retain(bits: i32) -> Self

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Self>

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

pub fn insert(&mut self, other: Self)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: Self)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: Self, value: bool)

Call insert when value is true or remove when value is false.

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: Self) -> Self

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl MultiSelectFlags

pub const fn iter(&self) -> Iter<MultiSelectFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<MultiSelectFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
