Trait SearchableStoreRead 

pub trait SearchableStoreRead<K: Ord, V>: OrderedStoreRead<K, V> {
    // Required method
    fn filter(&self, pred: impl FnMut(&K, &V) -> bool) -> Vec<(K, V)>;

    // Provided method
    fn find(&self, pred: impl FnMut(&K, &V) -> bool) -> Option<(K, V)> { ... }
}

Extension to a OrderedStoreRead, that allows looking through the store to look for specific entries,

Required Methods

fn filter(&self, pred: impl FnMut(&K, &V) -> bool) -> Vec<(K, V)>

Search for all entries in the store, that fulfill a certain predicate

Note that the elements are being searched through in the order specified by Ord of key

Arguments

• pred: A predicate that has access to the key and value

Returns

• An array of key-value pairs, for which pred holds true

Provided Methods

fn find(&self, pred: impl FnMut(&K, &V) -> bool) -> Option<(K, V)>

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.
