Enum EndpointError 

pub enum EndpointError {
    Empty,
    NoLeadingSlash,
    QueryOrFragment,
    NotVisibleAscii,
}

Why a path is not a usable endpoint.

Variants

Empty

The path was blank.

NoLeadingSlash

The path did not start with /.

Unit rather than carrying the offending path as a &'static str: the path came in as a borrowed &str with an arbitrary lifetime, so the only ways to carry it were to copy it into an owned allocation (for an error variant that fires once, at startup, on a value the caller still holds) or to name a lifetime on the error type. Neither is worth it — Endpoint is Copy-cheap to re-parse if the message is not specific enough, and the caller has the input.

QueryOrFragment

The path carried a ? or a #.

Neither survives the trip from a URL to a server: the client splits the fragment off before the request and the query into a separate component, so an endpoint containing either names a path that can never be requested. Accepting it would register a route that silently never fires, which is the same failure as a typo and is harder to spot.

NotVisibleAscii

The path held a byte that cannot appear in a request line.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
