//! Functions for converting a reference into a singleton slice.

//!
|
|
//! See also the ref_slice crate on crates.io.
|

|

//! We define the functions here to avoid external dependencies, and to ensure that they are

//! inlined in this crate.
|
|
//!
|
|
//! Despite their using an unsafe block, these functions are completely safe.
