Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<K: Value + Ord, V: Value> IncrBTreeMap<K, V> for Incr<BTreeMap<K, V>>

fn incr_merge<F, V2, R>( &self, other: &Incr<BTreeMap<K, V2>>, f: F, ) -> Incr<BTreeMap<K, R>>

where V2: Value, R: Value, F: FnMut(&K, MergeElement<&V, &V2>) -> Option<R> + 'static + NotObserver,

Merge two maps incrementally, where

• if a key appears only in self, the predicate runs with MergeElement::Left
• if a key appears only in other, the predicate runs with MergeElement::Right
• if a key appears in both, the predicate runs with MergeElement::Both

The predicate is only re-run for added/removed/modified keys in each map, using the symmetric diff property.

fn incr_mapi_<F, V2>(&self, f: F) -> Incr<BTreeMap<K, V2>>

where V2: Value, F: FnMut(&K, Incr<V>) -> Incr<V2> + 'static + NotObserver,

fn incr_mapi_cutoff<F, V2>( &self, f: F, cutoff: Cutoff<V>, ) -> Incr<BTreeMap<K, V2>>

where V2: Value, F: FnMut(&K, Incr<V>) -> Incr<V2> + 'static + NotObserver,

fn incr_filter_mapi_<F, V2>(&self, f: F) -> Incr<BTreeMap<K, V2>>

where V2: Value, F: FnMut(&K, Incr<V>) -> Incr<Option<V2>> + 'static + NotObserver,

fn incr_filter_mapi_cutoff<F, V2>( &self, f: F, cutoff: Cutoff<V>, ) -> Incr<BTreeMap<K, V2>>

where V2: Value, F: FnMut(&K, Incr<V>) -> Incr<Option<V2>> + 'static + NotObserver,
