Module mem 

Short lived memory.

For work whose size is not known until it runs, and which is finished with the memory by the time it returns. Allocating for each such call can cost more than the work itself.

Functions

take_slice

Takes a len element slice of T off the front of bytes, aligning first, and returns it along with what is left.

with_scratch

Calls f with a zeroed block of size bytes.

with_scratch_dyn 🔒

Calls f with a zeroed block of size bytes, through a trait object so that the buckets below are compiled once rather than once per caller.
