Struct rkyv::ser::serializers::AllocScratch

source · [−]

pub struct AllocScratch { /* private fields */ }

Expand description

Scratch space that always uses the global allocator.

This allocator will panic if scratch is popped that it did not allocate. For this reason, it should only ever be used as a fallback allocator.

source

impl AllocScratch
