Struct OccupiedEntry 

Source 
pub struct OccupiedEntry<'a, K: Key, V, S> { /* private fields */ }
Expand description

A type that represents an occupied entry in a slab.

Implementations§

Source§

impl<'a, K: Key, V, S> OccupiedEntry<'a, K, V, S>
where S: BuildHasher + Clone,

Source

pub fn key(&self) -> &K

Gets the key for this entry.

Source

pub fn offset(&self) -> usize

Gets the offset of the value in the slab.

Source

pub fn index(&self) -> Index<K, V>

Gets the index of the value in the slab.

Source

pub fn get(&self) -> &V

Gets a reference to the value for this entry.

Removes the link to this entry from the indeces map, returning the offset of the value in the slab.

§Safety

This does not remove the value from the slab. The actual value must be removed from the slab manually
