matcher.rs

1//! Proxy matchers
2//!
3//! This module contains different matchers to configure rules for when a proxy
4//! should be used, and if so, with what arguments.
5//!
6//! A [`Matcher`] can be constructed either using environment variables, or
7//! a [`Matcher::builder()`].
8//!
9//! Once constructed, the `Matcher` can be asked if it intercepts a `Uri` by
10//! calling [`Matcher::intercept()`].
11//!
12//! An [`Intercept`] includes the destination for the proxy, and any parsed
13//! authentication to be used.
