[][src]Enum std::alloc::AllocInit

pub enum AllocInit {
    Uninitialized,
    Zeroed,
}
🔬 This is a nightly-only experimental API. (allocator_api #32838)

A desired initial state for allocated memory.

Variants

Uninitialized
🔬 This is a nightly-only experimental API. (allocator_api #32838)

The contents of the new memory are uninitialized.

Zeroed
🔬 This is a nightly-only experimental API. (allocator_api #32838)

The new memory is guaranteed to be zeroed.

Implementations

impl AllocInit[src]

pub unsafe fn init(self, memory: MemoryBlock)[src]

🔬 This is a nightly-only experimental API. (allocator_api #32838)

Initialize the specified memory block.

This behaves like calling AllocInit::init_offset(memory, 0).

Safety

  • memory.ptr must be valid for writes of memory.size bytes.

pub unsafe fn init_offset(self, memory: MemoryBlock, offset: usize)[src]

🔬 This is a nightly-only experimental API. (allocator_api #32838)

Initialize the memory block like specified by init at the specified offset.

This is a no-op for AllocInit::Uninitialized and writes zeroes for AllocInit::Zeroed at ptr + offset until ptr + layout.size().

Safety

  • memory.ptr must be valid for writes of memory.size bytes.
  • offset must be smaller than or equal to memory.size
