Outcome

Enum Outcome 

Source
#[non_exhaustive]
pub enum Outcome { Served, Unauthenticated, NotFound, Malformed, Unavailable, }
Expand description

What happened to one request.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Served

The caller was authorised and got what it asked for.

§

Unauthenticated

The caller presented no usable credential.

§

NotFound

The caller is somebody, but not somebody who may read this — or nothing is served here. One outcome for both, because the server does not distinguish them to the caller and an audit log that did would be a way to ask it to.

§

Malformed

The request’s shape was refused before anything was looked up.

§

Unavailable

The caller was authorised and the section could not answer: it has no document yet, or a diagnostic could not read the sources. About the server, not about the caller — which is why it is not NotFound.

Source§

fn quirk(&self, value: Quirk) -> Painted<&T>
