[−][src]Enum lockfreehashmap::map_inner::KeyCompare

pub enum KeyCompare<'k, 'q, K: 'k + Borrow<Q>, Q: 'q + ?Sized> {
    Owned(NotNullOwned<KeySlot<K>>),
    Shared(NotNull<'k, KeySlot<K>>),
    OnlyCompare(&'q Q),
}

Sometimes when calling put_if_match() we want to insert a key and sometimes we just want to compare it with some variable of type Q. This enum represents which one is intended.

Methods

impl<'k, 'q, K: Borrow<Q>, Q: ?Sized> KeyCompare<'k, 'q, K, Q>
[src]

The purpose of this function is to ultimately get a value of type &Q. Because we need to call deref() and borrow() a few times, we need to put the result of these functions somewhere in order to return a reference. Thus, QRef and QRef2 are introduced as helper types to place these values somewhere.
