Struct KpThenAsyncKeyPath 

pub struct KpThenAsyncKeyPath<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second> { /* private fields */ }

Keypath that chains a sync keypath (crate::Kp) with an AsyncKeyPathLike. Use crate::Kp::then_async to create; then .get(&root).await.

Implementations

impl<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second> KpThenAsyncKeyPath<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second>

where First: SyncKeyPathLike<Root, Value, MutRoot, MutValue>, Second: AsyncKeyPathLike<Value, MutValue, Value = Value2, MutValue = MutValue2>,

pub async fn get(&self, root: Root) -> Option<Value2>

Get through sync keypath then async keypath (root is passed here).

pub async fn get_mut(&self, root: MutRoot) -> Option<MutValue2>

Get mutable through sync then async (root is passed here).

impl<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second> KpThenAsyncKeyPath<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second>

where First: SyncKeyPathLike<Root, Value, MutRoot, MutValue>, Second: AsyncKeyPathLike<Value, MutValue, Value = Value2, MutValue = MutValue2>,

pub fn then<V3, Value3, MutValue3, G3, S3>( self, next_kp: Kp<V2, V3, Value2, Value3, MutValue2, MutValue3, G3, S3>, ) -> AsyncKeyPathThenKp<R, V3, Root, Value3, MutRoot, MutValue3, Self, Kp<V2, V3, Value2, Value3, MutValue2, MutValue3, G3, S3>>

where V3: 'static, Value2: Borrow<V2>, MutValue2: BorrowMut<V2>, Value3: Borrow<V3>, MutValue3: BorrowMut<V3>, G3: Fn(Value2) -> Option<Value3> + Clone, S3: Fn(MutValue2) -> Option<MutValue3> + Clone,

Chain with a crate::Kp. Use .get(&root).await later.

Trait Implementations

where First: SyncKeyPathLike<Root, Value, MutRoot, MutValue>, Second: AsyncKeyPathLike<Value, MutValue, Value = Value2, MutValue = MutValue2>,

type Value = Value2

Value type at the end of the keypath.

type MutValue = MutValue2

Mutable value type at the end of the keypath.

fn get<'life0, 'async_trait>( &'life0 self, root: Root, ) -> Pin<Box<dyn Future<Output = Option<Value2>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get the value at the end of the keypath.

fn get_mut<'life0, 'async_trait>( &'life0 self, root: MutRoot, ) -> Pin<Box<dyn Future<Output = Option<MutValue2>> + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get mutable access to the value at the end of the keypath.

impl<R: Clone, V: Clone, V2: Clone, Root: Clone, Value: Clone, Value2: Clone, MutRoot: Clone, MutValue: Clone, MutValue2: Clone, First: Clone, Second: Clone> Clone for KpThenAsyncKeyPath<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second>

fn clone( &self, ) -> KpThenAsyncKeyPath<R, V, V2, Root, Value, Value2, MutRoot, MutValue, MutValue2, First, Second>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
