Enum matchit::MatchError

pub enum MatchError {
    MissingTrailingSlash,
    ExtraTrailingSlash,
    NotFound,
}

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);
}

Variants

Trait Implementations

impl Clone for MatchError

fn clone(&self) -> MatchError

Returns a copy of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MatchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for MatchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for MatchError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl PartialEq<MatchError> for MatchError

fn eq(&self, other: &MatchError) -> bool

This method tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
