[−][src]Struct light_arena::MemoryArena
Provides the backing storage to serve allocations requested by an Allocator
.
The MemoryArena
allocates blocks of fixed size on demand as its existing
blocks get filled by allocation requests. To make allocations in the
arena use the Allocator
returned by allocator
. Only one Allocator
can be active for an arena at a time, after the allocator is dropped
the space used by its allocations is made available again.
Methods
impl MemoryArena
[src]
pub fn new(block_size_mb: usize) -> MemoryArena
[src]
Create a new MemoryArena
with the requested block size (in MB).
The arena will allocate one initial block on creation, and further
blocks of block_size_mb
size, or larger if needed to meet a large
allocation, on demand as allocations are made.
pub fn allocator(&mut self) -> Allocator
[src]
Get an allocator for the arena. Only a single Allocator
can be
active for an arena at a time. Upon destruction of the Allocator
its allocated data is marked available again.
