[−][src]Enum sp_std::alloc::AllocInit
🔬 This is a nightly-only experimental API. (
allocator_api
)A desired initial state for allocated memory.
Variants
🔬 This is a nightly-only experimental API. (
allocator_api
)The contents of the new memory are uninitialized.
🔬 This is a nightly-only experimental API. (
allocator_api
)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
)Initialize the specified memory block.
This behaves like calling AllocInit::init_offset(memory, 0)
.
Safety
memory.ptr
must be valid for writes ofmemory.size
bytes.
pub unsafe fn init_offset(self, memory: MemoryBlock, offset: usize)
[src]
🔬 This is a nightly-only experimental API. (
allocator_api
)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 ofmemory.size
bytes.offset
must be smaller than or equal tomemory.size
