Struct MatchNodeChild 

pub struct MatchNodeChild { /* private fields */ }

Child node of match_node.

When the closure does not delegate to this node the delegation happens after the closure returns.

Implementations

impl MatchNodeChild

pub fn delegated(&mut self)

Flags the current operation as delegated, stopping the default delegation after the closure ends.

Note that each node operation methods already flags this.

pub fn has_delegated(&self) -> bool

If the current operation was already delegated to the child.

pub fn node(&mut self) -> &mut UiNode

Borrow the actual child.

Note that if you delegate using this reference you must call delegated.

pub fn node_impl<U: UiNodeImpl>(&mut self) -> &mut U

Borrow the actual child implementation.

Note that if you delegate using this reference you must call delegated.

Panics

Panics if the child node implementation does not match.
