Struct rkyv::collections::hash_set::ArchivedHashSet

#[repr(transparent)]
pub struct ArchivedHashSet<K>(_);

An archived HashSet. This is a wrapper around a hash map with the same key and a value of ().

Implementations

impl<K> ArchivedHashSet<K>

pub const fn len(&self) -> usize

Gets the number of items in the hash set.

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

Gets the key corresponding to the given key in the hash set.

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

Returns whether the given key is in the hash set.

pub fn hasher(&self) -> SeaHasher

Gets the hasher for the underlying hash map.

pub const fn is_empty(&self) -> bool

Returns whether there are no items in the hash set.

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

Gets an iterator over the keys of the underlying hash map.

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

Resolves an archived hash set from the 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

pub unsafe fn serialize_from_iter<'a, KU, S, I>(
    iter: I,
    serializer: &mut S
) -> Result<HashSetResolver, S::Error> where
    KU: 'a + Serialize<S, Archived = K> + Hash + Eq,
    S: Serializer + ScratchSpace + ?Sized,
    I: ExactSizeIterator<Item = &'a KU>, 

Serializes an iterator of keys as a hash set.

Safety

The keys returned by the iterator must be unique.
