source§fn allocate_segment(&mut self, minimum_size: u32) -> (*mut u8, u32)
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. Read moresource§fn deallocate_segment(
&mut self,
_ptr: *mut u8,
_word_size: u32,
_words_used: u32
)
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.Auto Trait Implementations§
