Structured error codes returned by the Signal Fish server.

Each variant corresponds to a specific error condition. The server sends these as "SCREAMING_SNAKE_CASE" strings (e.g., "ROOM_NOT_FOUND").

Use description() for a human-readable explanation.

SignalTargetNotFound

SignalRateLimited

SignalTooLarge

ConnectionIdleTimeout

SlowConsumer

The server evicted this connection because its outbound queue stayed full past the slow-consumer grace window (5 seconds by default): the client was not draining messages fast enough.

The farewell Error frame carrying this code is written best-effort into an already-congested socket, so it may never arrive; a bare disconnect can be the only observable signal. Wire: "SLOW_CONSUMER".

ActivityTimeout

The server closed the connection after prolonged protocol inactivity (no messages received within the activity window). Wire: "ACTIVITY_TIMEOUT".

ServerDraining

The server is draining for shutdown and rejecting new room creation. Existing connections close with semantic code 4000 at the deadline.

InvalidDeliveryClass

The requested protocol-v3 delivery class/key combination is invalid.

Implementations

impl ErrorCode

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

Returns a human-readable description of this error code.

This method provides actionable error messages that SDK developers can display to end users or use for debugging.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ErrorCode

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

Formats the value using the given formatter.

impl Eq for ErrorCode

impl PartialEq for ErrorCode

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for ErrorCode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
