Detailed Description

template<typename STACK_TRAITS>
struct Bloomberg::quantum::CoroutinePoolAllocator< STACK_TRAITS >

Provides fast (quasi zero-time) in-place allocation for coroutines. Coroutine stacks are pre-allocated from separate (i.e. non-contiguous) heap blocks and maintained in a reusable list.

Note

This allocator is thread safe. For internal use only and is meant to replace the boost fixed size pool allocator which crashes.
