Enum Error 

pub enum Error {
    Storage(StoreError),
    Config(ConfigError),
    Transient(TransientError),
    Transport(TransportError),
    InsufficientScope {
        reason: String,
    },
    InvalidGrant {
        reason: String,
    },
    InvalidClient {
        reason: String,
    },
    Revoked,
}

Canonical broker error exposed by public APIs.

Variants

Storage(StoreError)

Storage-layer failure.

Config(ConfigError)

Transient(TransientError)

Temporary upstream failure; retry with backoff.

Transport(TransportError)

Transport failure (DNS, TCP, TLS).

InsufficientScope

Requested scopes exceed what was granted.

Fields

reason: String

Provider- or broker-supplied reason string.

InvalidGrant

Provider rejected the grant (e.g., bad code or refresh token).

Fields

reason: String

Provider- or broker-supplied reason string.

InvalidClient

Client authentication failed or credentials are malformed.

Fields

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
