Fields

name: String

Name of the header to test, matched exactly against the header key.

pattern: String

Regular expression (Rust regex crate syntax) tested against the header value.

The value is matched as raw bytes, so non-UTF-8 values and byte patterns work. The pattern must match the entire value: it is anchored automatically, so ^/$ are unnecessary (though harmless). A header present with a null value is matched as an empty byte sequence; a header that appears more than once matches if any of its values match.
