Trait Implementations

impl Default for Top1MonoidRegion

fn default() -> Top1MonoidRegion

Returns the “default value” for a type.

impl Region for Top1MonoidRegion

type Item = Top1Monoid

The type of item the region contains.

unsafe fn copy(&mut self, item: &Self::Item) -> Self::Item

Add a new element to the region.

fn clear(&mut self)

Retain allocations but discard their contents.

fn reserve_items<'a, I>(&mut self, items1: I)

where Self: 'a, I: Iterator<Item = &'a Self::Item> + Clone,

Ensure that the region can absorb items without reallocation.

fn reserve_regions<'a, I>(&mut self, regions1: I)

where Self: 'a, I: Iterator<Item = &'a Self> + Clone,

fn heap_size(&self, callback: impl FnMut(usize, usize))

Determine this region’s memory used and reserved capacity in bytes.

fn with_capacity_items<'a, I>(items: I) -> Self

where Self: 'a, I: Iterator<Item = &'a Self::Item> + Clone,

Allocate an instance of Self that can absorb items without reallocation.

fn with_capacity_regions<'a, I>(regions: I) -> Self

where Self: 'a, I: Iterator<Item = &'a Self> + Clone,

Allocate an instance of Self that can absorb the items of regions without reallocation.
