Trait Implementations

impl Allocator for ZeroingHeapAllocator

fn allocate_segment(&mut self, minimum_size: u32) -> (*mut u8, u32)

Allocates zeroed memory for a new segment, returning a pointer to the start of the segment and a u32 indicating the length of the segment in words. The allocated segment must be at least minimum_size words long (minimum_size * 8 bytes long). Allocator implementations commonly allocate much more than the minimum, to reduce the total number of segments needed. A reasonable strategy is to allocate the maximum of minimum_size and twice the size of the previous segment.

unsafe fn deallocate_segment( &mut self, _ptr: *mut u8, _word_size: u32, _words_used: u32, )

Indicates that a segment, previously allocated via allocate_segment(), is no longer in use. word_size is the length of the segment in words, as returned from allocate_segment(). words_used is always less than or equal to word_size, and indicates how many words (contiguous from the start of the segment) were possibly written with non-zero values.

impl Debug for ZeroingHeapAllocator

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ZeroingHeapAllocator

fn default() -> Self

Returns the “default value” for a type.
