Enum ConnectionError 

#[non_exhaustive]
pub enum ConnectionError {
    UnknownProvider(String),
    OriginNotAllowed(String),
    BadState,
    NotFound(String),
    NeedsReconnect(String),
    Revoked,
    Provider(ProviderFailure),
    Config(String),
    Db(DbError),
}

What a connection call can fail with.

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.

UnknownProvider(String)

The provider key is not one this venture configured.

OriginNotAllowed(String)

The return_to is not on an allowed origin.

BadState

The state is unknown, spent or expired.

NotFound(String)

No connection carries the id.

NeedsReconnect(String)

The provider requires a fresh authorization.

Revoked

The connection was revoked.

Provider(ProviderFailure)

The provider’s token endpoint failed or answered with a non-token.

Config(String)

The module is misconfigured, or a sealed value could not be read.

Db(DbError)

A database failure.

Implementations

impl ConnectionError

pub fn slug(&self) -> &'static str

The RFC 9457 type slug this failure maps to, so a route the venture writes can answer the callback’s error=<slug> convention.

pub fn problem(&self) -> Problem

The problem body a caller should answer with.

pub fn provider_failure(&self) -> Option<&ProviderFailure>

The structured, safe facts of a provider failure, when this is one — what a log line records instead of the error’s Display.

Trait Implementations

impl Debug for ConnectionError

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

Formats the value using the given formatter.

impl Display for ConnectionError

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

Formats the value using the given formatter.

impl Error for ConnectionError

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

Returns 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>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<DbError> for ConnectionError

fn from(source: DbError) -> Self

Converts to this type from the input type.
