//! Outgoing body compression middleware for the [Tide][] server framework.
//!
//! ```rust
//! #[async_std::main]
//! async fn main() {
//!     let mut app = tide::new();
//!     app.with(tide_compress::CompressMiddleware::new());
//! }
//! ```
//!
//! ## Features
//!
//! - Support for [Brotli][], [Gzip][], and [Deflate][] encodings, compile-time configurable through cargo feature flags.
//!   - Prioritizes Brotli if available.
//!   - Only pulls in the necessary dependencies for the desired configuration.
//!   - Defaults to Brotli & Gzip.
//!   - Also handles the `"identity"` encoding directive [as per RFC 9110][Identity].
//! - [`Accept-Encoding`][] header checking including priority.
//! - Minimum body size threshold (Default: 1024 bytes, configurable).
//! - Does not compress responses with a [`Cache-Control: no-transform`][] header.
//! - Sets the [`Vary`][] header.
//! - Checks the [`Content-Type`][] header (MIME).
//!   - Checks against [jshttp's comprehensive database][jshttp mime-db], which is compiled to a [perfect hash function][].
//!   - The database can be regenerated in the crate's repository by running `cargo run generate-database`.
//!   - If not in the database, checks against a regular expression.
//!     - Default: `^text/|\+(?:json|text|xml)$` (case insensitive).
//!     - Fully override-able to any custom [`Regex`][], with `None` as an option.
//!   - Functionality can be excluded in crate features if the `regex` crate poses build issues.
