Struct TopicMatch 

pub struct TopicMatch { /* private fields */ }

The result of matching a TopicPath against a pattern.

Holds the matched topic plus the ranges of segments captured by the pattern’s wildcards, accessible by position (get_param) or by name (get_named_param).

Implementations

impl TopicMatch

pub fn path_segments(&self) -> &Vec<Substr>

Returns the matched topic’s segments.

pub fn get_param(&self, index: usize) -> Option<Substr>

Returns the positional parameter captured at index, if any.

Parameters are numbered in pattern order; a # wildcard yields the joined remainder of the topic.

pub fn get_named_param(&self, name: &str) -> Option<Substr>

Returns the value of the named parameter name, if the pattern bound one.

pub fn topic_path(&self) -> ArcStr

Returns a cheap (refcounted) clone of the matched topic string.
