Expand description

TLSFアロケータの実体を保持し、確保・解放および使用量計測を行う内部構造体。

Fields§

§tlsf: Tlsf<'static, u32, u16, 25, 16>§total: usize§used: usize

Implementations§

Source§

impl TlsfHeap

Source

const fn empty() -> Self

空のアロケータ実体を初期生成します。

Source

unsafe fn init(&mut self, start: usize, size: usize)

メモリプールを登録してヒープ領域を初期化します。

§Safety

与えられた start アドレスから size バイトのメモリ領域が、排他的に利用可能な物理アドレス領域である必要があります。

Source

unsafe fn alloc(&mut self, layout: Layout) -> *mut u8

Source

unsafe fn dealloc(&mut self, ptr: NonNull<u8>, layout: Layout)

Source

fn free_space(&self) -> usize
