Struct AppendOnlyHashMap

pub struct AppendOnlyHashMap<K, V>(/* private fields */);

Like std::collections::HashMap, but append-only.

Implementations

impl<K, V> AppendOnlyHashMap<K, V>

pub fn new() -> Self

Creates an empty AppendOnlyHashMap.

pub fn with_capacity(capacity: usize) -> Self

Creates an empty AppendOnlyHashMap with the specified capacity.

impl<K, V> AppendOnlyHashMap<K, V>

where K: Eq + Hash,

pub fn get<'map, Q>(&'map self, key: &Q) -> Option<&'map V>

where Q: Borrow<K> + ?Sized,

Returns a reference to the value corresponding to the key.

pub fn get_or_insert_with<'map, F>(&'map self, key: K, f: F) -> &'map V

where F: FnOnce(&K) -> V,

Returns a reference to the value corresponding to the key, invoking the provided callback if it is not already present.

pub fn get_or_insert_with_fallible<'map, E, F>( &'map self, key: K, f: F, ) -> Result<&'map V, E>

where F: FnOnce(&K) -> Result<V, E>,

Returns a reference to the value corresponding to the key, invoking the provided callback if it is not already present.
