Struct HeaderRules 

pub struct HeaderRules(/* private fields */);

The header predicates of one route-table rule (sozu-proxy/sozu#1253): a conjunction, empty for a rule without predicates.

It is part of the rule’s identity: Router’s add and remove paths compare it alongside the path and method, so a canary rule that differs from its base only by a predicate coexists with it, and removing one leaves the other. The rules are kept in a canonical order, so two spellings of one conjunction (other declaration order, other name case) are one rule — the same canonicalisation the ConfigState key applies (RequestHttpFrontend’s Display in command/src/request.rs).

Implementations

impl HeaderRules

pub fn from_config(predicates: &[HeaderPredicate]) -> Result<Self, RouterError>

Compile a frontend’s predicates, held to validate_header_predicate first. A regex value is compiled anchored, refused when it does not compile exactly like a REGEX path rule (the private anchored_regex helper compiles both).

pub fn is_empty(&self) -> bool

pub fn matches(&self, headers: &dyn RequestHeaders) -> bool

Whether every predicate holds for headers. True for an empty conjunction, which never reads headers.
