//! Provides constant functions to compute for `ioctl(2)` identifiers.
//!
//! Currently, this supports Linux and macOS. The long term goal is to support `ioctl` identifiers for other BSD
//! variants.
//!
//! ## Usage Notes
//! [`IoctlId`] is an alias for the type to pass into the `ioctl(2)` request. This is either a `u32` or `u64`, depending
//! on the target OS and architecture.
//!
//! The [`io()`], [`ior()`], [`iow()`], and [`iowr()`] functions take a type parameter, similar to the `_IO()`,
//! `_IOR()`, `_IOW()`, and `_IOWR()` macros.
//!
//! For example, the following C code:
//! ```c
//! struct my_ioctl_data {
//! unsigned int a;
//! };
//!
//! #define MY_IOCTL _IOR(0x12, 0x34, struct my_ioctl_data)
//! ```
//!
//! Would be written in Rust as:
//! ```rust
//! use ioctl_id::*;
//!
//! #[repr(C)]
//! struct MyIoctlData {
//! a: u32,
//! }
//!
//! const MY_IOCTL: IoctlId = ior::<MyIoctlData>(0x12, 0x34);
//! ```
