A custom allocator that allows a singular allocation of a specific size known ahead of time.

For situations where one allocation is required, but otherwise allocations are not allowed (usually for constrained embedded devices). Extremely small (only 32 lines of code).

This example allocates once by creating an Arc of the unit tuple (). Requires libc for printing, but can be replaced with a serial port implementation.

Run with cargo +nightly run --example main from within the repo.
