Struct Loader 

pub struct Loader<K, V, F>
where
    K: Eq + Hash + Clone,
    V: Clone,
    F: BatchFn<K, V>,
{ /* private fields */ }

Implementations

impl<K, V, F> Loader<K, V, F>

where K: Eq + Hash + Clone + Debug, V: Clone, F: BatchFn<K, V>,

pub fn new(load_fn: F) -> Loader<K, V, F>

pub fn with_max_batch_size(self, max_batch_size: usize) -> Self

pub fn with_yield_count(self, yield_count: usize) -> Self

pub fn with_custom_wait_for_work(self, wait_for_work_fn: impl WaitForWorkFn)

Replaces the yielding for work behavior with an arbitrary future. Rather than yielding the runtime repeatedly this will generate and .await a future of your choice. This is incompatible with Self::with_yield_count().

pub fn max_batch_size(&self) -> usize

pub async fn try_load(&self, key: K) -> Result<V, Error>

pub async fn load(&self, key: K) -> V

pub async fn load_many(&self, keys: Vec<K>) -> HashMap<K, V>

pub async fn try_load_many(&self, keys: Vec<K>) -> Result<HashMap<K, V>, Error>

Trait Implementations

impl<K, V, F> Clone for Loader<K, V, F>

where K: Eq + Hash + Clone, V: Clone, F: BatchFn<K, V>,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
