Struct rkyv::collections::index_map::ArchivedIndexMap

pub struct ArchivedIndexMap<K, V> { /* fields omitted */ }

An archived IndexMap.

Implementations

impl<K, V> ArchivedIndexMap<K, V>

pub fn contains_key<Q: ?Sized>(&self, k: &Q) -> bool where
    K: Borrow<Q>,
    Q: Hash + Eq, 

Returns whether a key is present in the hash map.

pub fn first(&self) -> Option<(&K, &V)>

Returns the first key-value pair.

pub fn get<Q: ?Sized>(&self, k: &Q) -> Option<&V> where
    K: Borrow<Q>,
    Q: Hash + Eq, 

Gets the value associated with the given key.

pub fn get_full<Q: ?Sized>(&self, k: &Q) -> Option<(usize, &K, &V)> where
    K: Borrow<Q>,
    Q: Hash + Eq, 

Gets the index, key, and value associated with the given key.

pub fn get_index(&self, index: usize) -> Option<(&K, &V)>

Gets a key-value pair by index.

pub fn get_index_of<Q: ?Sized>(&self, key: &Q) -> Option<usize> where
    K: Borrow<Q>,
    Q: Hash + Eq, 

Gets the index of a key if it exists in the map.

pub fn get_key_value<Q: ?Sized>(&self, k: &Q) -> Option<(&K, &V)> where
    K: Borrow<Q>,
    Q: Hash + Eq, 

Gets the key-value pair associated with the given key.

pub fn hasher(&self) -> HashBuilder

Gets the hasher for this index map.

pub const fn is_empty(&self) -> bool

Returns true if the map contains no elements.

pub fn iter(&self) -> Iter<'_, K, V>

Returns an iterator over the key-value pairs of the map in order

pub fn keys(&self) -> Keys<'_, K, V>

Returns an iterator over the keys of the map in order

pub fn last(&self) -> Option<(&K, &V)>

Returns the last key-value pair.

pub const fn len(&self) -> usize

Gets the number of items in the index map.

pub fn values(&self) -> Values<'_, K, V>

Returns an iterator over the values of the map in order.

pub unsafe fn resolve_from_len(
    len: usize,
    pos: usize,
    resolver: IndexMapResolver,
    out: *mut Self
)

Resolves an archived index map from a given length and parameters.

Safety

• len must be the number of elements that were serialized
• pos must be the position of out within the archive
• resolver must be the result of serializing a hash map
