[][src]Struct capnp::message::ScratchSpaceHeapAllocator

pub struct ScratchSpaceHeapAllocator<'a> { /* fields omitted */ }

An Allocator whose first segment is a backed by a user-provided buffer.


impl<'a> ScratchSpaceHeapAllocator<'a>[src]

pub fn new(scratch_space: &'a mut [u8]) -> ScratchSpaceHeapAllocator<'a>[src]

Writes zeroes into the entire buffer and constructs a new allocator from it.

If you want to reuse the same buffer and to minimize the cost of zeroing for each message, you can call message::Builder::into_allocator() to recover the allocator from the previous message and then pass it into the new message.

pub fn second_segment_words(self, value: u32) -> ScratchSpaceHeapAllocator<'a>[src]

pub fn allocation_strategy(
    value: AllocationStrategy
) -> ScratchSpaceHeapAllocator<'a>
