Struct HeapMemory 

pub struct HeapMemory { /* private fields */ }

堆内存操作

Implementations

impl HeapMemory

pub fn new( flags: HEAP_FLAGS, initial_size: usize, maximum_size: usize, ) -> Result<Self>

创建新实例。 flags 内存标志。 size 内存大小（字节数）。

pub fn alloc(&self, size: usize) -> *mut c_void

分配内存。 size 要分配的大小。

pub fn free(&self, mem: *const c_void) -> bool

释放内存。 mem 内存指针。

Trait Implementations

impl Default for HeapMemory

fn default() -> Self

Returns the “default value” for a type.

impl Drop for HeapMemory

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
