Struct NodeCapabilities 

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

Capability flags indicating which specialized traits a modifier node implements.

Implementations

impl NodeCapabilities

pub const NONE: NodeCapabilities

No capabilities.

pub const LAYOUT: NodeCapabilities

Modifier participates in measure/layout.

pub const DRAW: NodeCapabilities

Modifier participates in draw.

pub const POINTER_INPUT: NodeCapabilities

Modifier participates in pointer input.

pub const SEMANTICS: NodeCapabilities

Modifier participates in semantics tree construction.

pub const MODIFIER_LOCALS: NodeCapabilities

Modifier participates in modifier locals.

pub const FOCUS: NodeCapabilities

Modifier participates in focus management.

pub const WINDOW_ROOT: NodeCapabilities

Modifier makes its node the root of a separate window: the node’s subtree is laid out into that window’s size and drawn into that window’s scene, and the parent’s scene skips it.

pub const fn empty() -> NodeCapabilities

Returns an empty capability set.

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

Returns whether all bits in other are present in self.

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

Returns whether any bit in other is present in self.

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

Inserts the requested capability bits.

pub const fn bits(self) -> u32

Returns the raw bit representation.

pub const fn is_empty(self) -> bool

Returns true when no capabilities are set.

pub const fn for_invalidation(kind: InvalidationKind) -> NodeCapabilities

Returns the capability bit mask required for the given invalidation.
