mcu-if

This crate facilitates the most common Rust programming APIs to be used under no_std MCU firmware development.

Specifically, it provides:

a no_std equivalent of the standard Rust APIs such as println!, alloc::{boxed::Box, vec, vec::Vec}, and io::{Cursor, Seek, SeekFrom, Write, ...} assuming that the #[global_allocator] requirement can be satisfied by using target MCU's malloc() and free() C API.
base implementations of #[panic_handler] and #[alloc_error_handler] that are required when no_std Rust code is based on the custom #[global_allocator] above.

For a practical firmware example based on RIOT-OS, see the xbd-base demo.

This crate requires Rust nightly.
