Struct dynvec::region::block::Block

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

A contiguous region of the memory.

Implementations

impl<H> Block<H>

pub fn new(length: usize) -> Self

Creates a new Block that is length bytes long.

pub fn for_layouts(iter: impl IntoIterator<Item = Layout>) -> Self

Creates a new empty Block that is large enough to store each layout.

Trait Implementations

impl<H> Region<H> for Block<H>

type Pointers = IntoIter<*mut u8>

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.
