Struct HashTableCursorMut 

pub struct HashTableCursorMut<'a, K, P, B = SinglyLinkedList<P>, H = DefaultHashTraits>
where
    P: PtrTraits,
    P::Target: HashTableKeyable<K>,
    B: HashTableBucket<P>,
    K: Eq,
    H: HashTraits<K>,
{ /* private fields */ }

A cursor positioned at an element of a HashTable (or at no element), which can be used to access or erase that element.

Returned by HashTable::find_cursor and HashTable::insert_or_find.

Implementations

impl<'a, K, P, B, H> HashTableCursorMut<'a, K, P, B, H>

where P: PtrTraits, P::Target: HashTableKeyable<K>, B: HashTableBucket<P>, K: Eq, H: HashTraits<K>,

pub fn get(&self) -> Option<&P::Target>

Returns a reference to the element the cursor is positioned at, or None if it is not positioned at any element.

pub fn erase(self) -> Option<P>

Erases the element the cursor is positioned at from the hash table, returning it.

Returns None if the cursor is not positioned at any element.
