pub struct Map<K: 'static, V: 'static> { /* private fields */ }
Expand description
An immutable map constructed at compile time.
Note
The fields of this struct are public so that they may be initialized by the
phf_map!
macro and code generation. They are subject to change at any
time and should never be accessed directly.
Implementations§
source§impl<K, V> Map<K, V>
impl<K, V> Map<K, V>
sourcepub fn contains_key<T>(&self, key: &T) -> boolwhere
T: Eq + PhfHash + ?Sized,
K: PhfBorrow<T>,
pub fn contains_key<T>(&self, key: &T) -> boolwhere T: Eq + PhfHash + ?Sized, K: PhfBorrow<T>,
Determines if key
is in the Map
.
sourcepub fn get<T>(&self, key: &T) -> Option<&V>where
T: Eq + PhfHash + ?Sized,
K: PhfBorrow<T>,
pub fn get<T>(&self, key: &T) -> Option<&V>where T: Eq + PhfHash + ?Sized, K: PhfBorrow<T>,
Returns a reference to the value that key
maps to.
sourcepub fn get_key<T>(&self, key: &T) -> Option<&K>where
T: Eq + PhfHash + ?Sized,
K: PhfBorrow<T>,
pub fn get_key<T>(&self, key: &T) -> Option<&K>where T: Eq + PhfHash + ?Sized, K: PhfBorrow<T>,
Returns a reference to the map’s internal static instance of the given key.
This can be useful for interning schemes.
sourcepub fn get_entry<T>(&self, key: &T) -> Option<(&K, &V)>where
T: Eq + PhfHash + ?Sized,
K: PhfBorrow<T>,
pub fn get_entry<T>(&self, key: &T) -> Option<(&K, &V)>where T: Eq + PhfHash + ?Sized, K: PhfBorrow<T>,
Like get
, but returns both the key and the value.
sourcepub fn entries(&self) -> Entries<'_, K, V> ⓘ
pub fn entries(&self) -> Entries<'_, K, V> ⓘ
Returns an iterator over the key/value pairs in the map.
Entries are returned in an arbitrary but fixed order.
