//! This module contains a number of lookup tables.
//!
//! Any of this lookup tables can be enabled by a feature. The additive property of
//! rust features has the effect, that if multiple crates require (a semver compatible
//! version of) lut the compiler will include only one instance of lut into the binary
//! with all features enabled which are enabled in any of the crates. As such any
//! lookup table will should only appear one time in the resulting binary.
//!
//! The benefit of having a collection of "generalish" lookup tables in on crate is that:
//!
//! 1. crates can share the same tables, even if they e.g. implement different parser algorithm
//!    decresing developer overhead and code size (if they are used in the same binary)
//! 2. developers have a place where they can look for them improving discoverability

/// a lookup table for parsing/validating Media Types (also know as MIME-Types)
///
/// To use lookup the table compile the crate with the `media-type-chars` feature enabled,
/// else wise this module will be empty.
