Enum DiscoveryError 

#[non_exhaustive]
pub enum DiscoveryError {
    InvalidIssuerUrl(ParseError),
    Http(HttpError),
    Status(u16),
    Parse(Error),
    IssuerMismatch,
}

A failure while fetching OpenID Connect provider metadata from a .well-known/openid-configuration document.

Variants (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.

InvalidIssuerUrl(ParseError)

The issuer URL could not be turned into a discovery URL.

Http(HttpError)

The metadata request failed at the transport layer.

Status(u16)

The discovery endpoint returned a non-2xx status.

Parse(Error)

The metadata document could not be deserialized.

IssuerMismatch

The issuer in the metadata did not match the requested issuer URL (OpenID Connect Discovery §4.3) — a misconfigured or hostile provider.
