Struct PathParams 

pub struct PathParams(pub Vec<(String, String)>);

Extracted path parameters stored in request extensions.

This type is set by the router after matching a route and extracting path parameters. The Path extractor retrieves this from the request.

Example

For a route /users/{user_id}/posts/{post_id} matched against /users/42/posts/99, this would contain: [("user_id", "42"), ("post_id", "99")]

Tuple Fields

0: Vec<(String, String)>
