Trait webpack_q::prelude::Query

pub trait Query<I, V> where
    I: Identity,
    V: Identifiable<I>, {
    fn query(&self, identifier: &I) -> Option<&V>;
    fn all(&self) -> Vec<&V, Global>;

    fn create_index(&self) -> HashMap<I, Link<'_, I, V>, RandomState> { ... }
}

Be able to query some type given an identifier. It must return a type that can be queried for more values like itself.

Query a datastore for a type that can be used to find more like it

Required Methods

fn query(&self, identifier: &I) -> Option<&V>

fn all(&self) -> Vec<&V, Global>

Provided Methods

fn create_index(&self) -> HashMap<I, Link<'_, I, V>, RandomState>
