Enum MatchError

Source
pub enum MatchError {
    MissingTrailingSlash,
    ExtraTrailingSlash,
    NotFound,
}
Expand description

A failed match attempt.

use matchit::{MatchError, Router};
let mut router = Router::new();
router.insert("/home", "Welcome!")?;
router.insert("/blog/", "Our blog.")?;

// a route exists without the trailing slash
if let Err(err) = router.at("/home/") {
    assert_eq!(err, MatchError::ExtraTrailingSlash);
}

// a route exists with a trailing slash
if let Err(err) = router.at("/blog") {
    assert_eq!(err, MatchError::MissingTrailingSlash);
}

// no routes match
if let Err(err) = router.at("/foobar") {
    assert_eq!(err, MatchError::NotFound);
}
