Struct ProjectedBinding 

pub struct ProjectedBinding<Root: 'static, Focus: 'static, SK> { /* private fields */ }

A field projected from a StateBinding through a keypath.

Implementations

impl<Root, Focus, SK> ProjectedBinding<Root, Focus, SK>

where Root: 'static, Focus: 'static, SK: RefKpTrait<Root, Focus>,

pub fn with<R>(&self, f: impl FnOnce(&Focus) -> R) -> Option<R>

Borrow the focused value under the root lock, or None if the keypath misses.

pub fn with_mut<R>(&self, f: impl FnOnce(&mut Focus) -> R) -> Option<R>

Mutably borrow the focused value under the root lock, or None if the keypath misses.

pub fn project<V, SubSK>( self, sub_kp: SubSK, ) -> ComposedBinding<Root, Focus, V, SK, SubSK>

where SubSK: RefKpTrait<Focus, V>, SK: Clone,

Chain another keypath segment (consumes self; parent keypath must be Clone).

Trait Implementations

impl<Root, Focus, SK> Clone for ProjectedBinding<Root, Focus, SK>

where Root: 'static, Focus: 'static, SK: RefKpTrait<Root, Focus> + Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
