Trait flatk::Reserve[−][src]

pub trait Reserve {
    fn reserve_with_storage(&mut self, n: usize, storage_n: usize);

    fn reserve(&mut self, n: usize) { ... }
}
Expand description

A trait that allows the container to allocate additional space without changing any of the data. The container should allocate space for at least n additional elements.

Composite collections such a Chunked or Select may choose to only reserve primary level storage if the amount of total storage required cannot be specified by a single number in reserve. This is the default behaviour of the reserve function below. The reserve_with_storage method allows the caller to also specify the amount of storage needed for the container at the lowest level.
