[−][src]Struct xalloc::bitmap::BitmapAlloc
Free space bitmap-based external memory allocator.
See the module-level documentation for more.
Implementations
impl BitmapAlloc[src]
pub fn new(size: usize) -> Self[src]
Construct a BitmapAlloc.
pub fn alloc(&mut self, size: usize) -> Option<(BitmapAllocRegion, usize)>[src]
Alias of alloc_next.
pub fn alloc_next(&mut self, size: usize) -> Option<(BitmapAllocRegion, usize)>[src]
Allocate a region of the size size using a Next-Fit strategy.
The time complexity is linear to the size of the heap.
Returns a handle of the allocated region and its offset if the
allocation succeeds. Returns None otherwise.
size must not be zero.
pub fn alloc_first(&mut self, size: usize) -> Option<(BitmapAllocRegion, usize)>[src]
Allocate a region of the size size using a First-Fit strategy.
The time complexity is linear to the size of the heap.
Returns a handle of the allocated region and its offset if the
allocation succeeds. Returns None otherwise.
size must not be zero.
pub fn dealloc_relaxed(&mut self, r: BitmapAllocRegion)[src]
Deallocate the specified region.
r must originate from the same instance of BitmapAlloc. Otherwise,
BitmapAlloc enters an inconsistent state and possibly panics, but does
not cause an undefined behavior.
