Struct Options

Source
pub struct Options<M, S>
where S: BuildHasher,
{ /* private fields */ }
Expand description

Options for how to initialize the map.

In particular, the options dictate the hashing function, meta type, and initial capacity of the map.

Implementations§

Source§

impl<M, S> Options<M, S>
where S: BuildHasher,

Source

pub fn with_meta<M2>(self, meta: M2) -> Options<M2, S>

Set the initial meta value for the map.

Source

pub fn with_hasher<S2>(self, hash_builder: S2) -> Options<M, S2>
where S2: BuildHasher,

Set the hasher used for the map.

Source

pub fn with_capacity(self, capacity: usize) -> Options<M, S>

Set the initial capacity for the map.

Source

pub fn construct<K, V>( self, ) -> (ReadHandle<K, V, M, S>, WriteHandle<K, V, M, S>)
where K: Eq + Hash + Clone, S: BuildHasher + Clone, V: Eq + Hash + ShallowCopy, M: 'static + Clone,

Create the map, and construct the read and write handles used to access it.
