Struct dynvec::region::chunks::Chunks

pub struct Chunks<H> { /* fields omitted */ }

Reallocates new chuncks when it gets too small to allocate new objects.

Implementations

impl<H> Chunks<H>

pub fn new(min_chunk_size: usize) -> Self

Creates a new instance of Chunks. No chunks will be allocated until an object is allocated.

Note that chunks may need to allocate more memory than min_chunk_size to store allocate a large number of bytes.

pub fn with_chuncks(min_chunk_size: usize, chunk_count: usize) -> Self

Creates a new instance of Chuncks. This function allocates chunk_count chunks in advance.

Trait Implementations

impl<H> Region<H> for Chunks<H>

type Pointers = Flatten<IntoIter<<Block<H> as Region<H>>::Pointers>>

An iterator over all the allocations of this region.

pub fn allocate(&mut self, layout: Layout, header: H) -> Result<*mut u8, H>

Finds a free location within this region that is:

pub fn deallocate(&mut self, ptr: *mut u8) -> Option<H>

Deallocates the memory allocated at the given pointer.

pub fn has_allocated(&self, ptr: *mut u8) -> bool

Checks whether the given pointer is allocated in this region.

pub fn count(&self) -> usize

Returns the number of allocations this region has.

pub fn allocations(&self) -> Self::Pointers

Returns an iterator over all the allocations of this region.

pub fn deallocate_all(&mut self) -> DeallocateAll<'_, H, Self> where
    Self: Sized, 

Returns an iterator that causes all allocations to be deallocated. The iterator yield the headers.
