Crate lockedbox

LockedBox

A crate providing an mlock-locked Box<T>, preventing the contents of its memory from being paged to disk.

This crate prevents potential accidental unlocking of memory by ensuring the memory allocated by LockedBox<T> is always a multiple of the operating system’s page size. Because mlock/munlock operate on pages of memory, this guarantees that each LockedBox<T> is guaranteed to have its own lock status.

LockedBox<T> is a thin, safe abstraction built atop memsec.
