pub struct VecMap<K, V>(Vec<(K, V)>);
Expand description

A map type implemented as a vector of pairs K (key) and V (value). It currently provides a subset of all the map operations, the rest could be added as needed.

§0: Vec<(K, V)>

Implementations§

Sets the value of the entry, and returns the entry’s old value.

Removes the entry from the map and returns the removed value

Gets a reference to the value in the entry.

Gets a mutable reference to the value in the entry.

Returns the any value corresponding to the supplied predicate filter.

The supplied predicate will be applied to each (key, value) pair and it will return a reference to the values where the predicate returns true.

Returns the value corresponding to the supplied predicate filter. It crashes if there’s more than one matching element.

The supplied predicate will be applied to each (key, value) pair and it will return a reference to the value where the predicate returns true.

Returns true if the map contains a value for the specified key.

The key may be any borrowed form of the map’s key type, Eq on the borrowed form must match those for the key type.

Returns true if the map contains no elements.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
