Struct timely::container::columnation::StableRegion

source ·
pub struct StableRegion<T> { /* private fields */ }
Expand description

A region allocator which holds items at stable memory locations.

Items once inserted will not be moved, and their locations in memory can be relied on by others, until the region is cleared.

This type accepts owned data, rather than references, and does not itself intend to implement Region. Rather, it is a useful building block for other less-safe code that wants allocated data to remain at fixed memory locations.

Implementations§

source§

impl<T> StableRegion<T>

source

pub fn with_limit(limit: usize) -> StableRegion<T>

Construct a StableRegion with a allocation size limit.

source

pub fn clear(&mut self)

Clears the contents without dropping any elements.

source

pub fn copy_iter<I>(&mut self, items: I) -> &mut [T]
where I: Iterator<Item = T> + ExactSizeIterator,

Copies an iterator of items into the region.

source

pub fn copy_slice(&mut self, items: &[T]) -> &mut [T]
where T: Clone,

Copies a slice of cloneable items into the region.

source

pub fn reserve(&mut self, count: usize)

Ensures that there is space in self.local to copy at least count items.

source

pub fn with_capacity(count: usize) -> StableRegion<T>

Allocates a new Self that can accept count items without reallocation.

source

pub fn len(&self) -> usize

The number of items current held in the region.

source

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