Struct PathPattern 

pub struct PathPattern { /* private fields */ }

A compiled route path pattern (/users/:id) — a sequence of static and :param [Segment]s. Matched against a run of Location segments by match_prefix; the router composes nested patterns by matching parent then child against successive segment runs.

Implementations

impl PathPattern

pub fn parse(pattern: &str) -> PathPattern

Compile a pattern string into segments (trailing/leading slashes ignored). A :name segment is a parameter capture; everything else is static.

pub fn len(&self) -> usize

The number of segments this pattern consumes.

pub fn is_empty(&self) -> bool

Whether this pattern is empty (an index/root pattern that consumes no segments — e.g. a / route or a path-less shell route).

pub fn match_prefix(&self, segs: &[String]) -> Option<(usize, RouteParams)>

Try to match this pattern as a prefix of segs, capturing every :param. Returns (consumed, params) — the number of leading segments consumed (always self.len()) and the captured params — or None if a static segment mismatches or there are too few segments to cover the pattern.

Prefix (not whole-slice) matching is what lets nested routes compose: a parent consumes its segments, then the router feeds the remainder to the child.
