Struct pavex::request::path::MatchedPathPattern

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

The route template that matched for the incoming request.

Example

If you configure your Blueprint like this:

use pavex::{f, blueprint::{Blueprint, router::GET}};

bp.route(GET, "/home/:home_id", f!(crate::get_home));

Then MatchedPathPattern will be set to /home/:home_id for a GET /home/123 request.

Framework primitive

MatchedPathPattern is a framework primitive—you don’t need to register any constructor with Blueprint to use it in your application.

Use cases

The primary use case for MatchedPathPattern is telemetry—logging, metrics, etc.
It lets you strip away the dynamic parts of the request path, thus reducing the cardinality of your metrics and making it easier to aggregate them.

Implementations

impl MatchedPathPattern

pub fn new(route: &'static str) -> Self

Example

use pavex::request::path::MatchedPathPattern;

let matched_route = MatchedPathPattern::new("/home/:home_id");

pub fn inner(self) -> &'static str

Get a reference to the underlying route template.
