//! Common operations and types in Tock.
//!
//! These are data types and access mechanisms that are used throughout the Tock
//! kernel. Mostly they simplify common operations and enable the other parts of
//! the kernel (chips and capsules) to be intuitive, valid Rust. In some cases
//! they provide safe wrappers around unsafe interface so that other kernel
//! crates do not need to use unsafe code.
