Comprehensive error taxonomy for relay operations

Variants

AuthenticationFailed

Authentication failed due to invalid token or signature

Fields

reason: String

Human-readable reason for authentication failure

RateLimitExceeded

Rate limiting triggered - too many requests

Fields

retry_after_ms: u64

Suggested wait time before retrying, in milliseconds

SessionError

Session-related errors

Fields

session_id: Option<u32>

Optional session identifier if known

kind: SessionErrorKind

Specific category of session error

NetworkError

Network connectivity issues

Fields

operation: String

The operation being performed when the error occurred

source: String

The underlying error source description

ProtocolError

Protocol-level errors

Fields

frame_type: u8

Offending frame type identifier

reason: String

Human-readable explanation of the violation

ResourceExhausted

Resource exhaustion (memory, bandwidth, etc.)

Fields

resource_type: String

Type of resource that was exceeded (e.g. “buffer”, “sessions”)

current_usage: u64

Current measured usage of the resource

limit: u64

Configured limit for the resource

ConfigurationError

Configuration or setup errors

Fields

parameter: String

The configuration parameter that is invalid

reason: String

Explanation of why the parameter is invalid

Trait Implementations

impl Clone for RelayError

fn clone(&self) -> RelayError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RelayError

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

Formats the value using the given formatter.

impl Display for RelayError

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

Formats the value using the given formatter.

impl Error for RelayError

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<Error> for RelayError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for RelayError

fn eq(&self, other: &RelayError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
