EventMask

Struct EventMask 

Source
pub struct EventMask(/* private fields */);
Expand description

A set of pending EventFlags conditions.

The representation is exactly one u32: bit indices 0 through 31 are the complete condition namespace. Applications can define named const masks with EventMask::from_bits without introducing a runtime mapping layer.

Implementations§

Source§

impl EventMask

Source

pub const EMPTY: Self

The empty condition set.

Source

pub const ALL: Self

The set containing all 32 conditions.

Source

pub const fn from_bits(bits: u32) -> Self

Construct a mask from its exact 32-bit representation.

Source

pub const fn from_index(index: u32) -> Option<Self>

Construct the one-condition mask at index.

Returns None for an index outside 0..32; no shift panic is reachable, including on a hot path that validates external input.

Source

pub const fn bits(self) -> u32

Return the exact 32-bit representation.

Source

pub const fn is_empty(self) -> bool

Whether the set contains no conditions.

Source

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

Whether every condition in other is present in this set.

Source

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

Whether this set and other share at least one condition.
