Enum StationError 

pub enum StationError {
    NotBuilt,
    Subscribe(String),
    StreamNotSupported(String),
    Core(String),
    Io(Error),
}

Variants

NotBuilt

Subscribe(String)

StreamNotSupported(String)

The exchange does not expose this stream on the WS wire. Subscribe MUST NOT spawn a forwarder for this combination — heal/resub would loop forever. Surfaced from subscribe_frame returning either WebSocketError::NotSupported or WebSocketError::UnsupportedOperation. Consumers should treat this as a quiet “skip” rather than a hard failure: it’s an architectural fact about the venue, not a runtime fault.

Core(String)

Io(Error)

Implementations

impl StationError

pub fn is_not_supported(&self) -> bool

True when this error originates from the venue not exposing the requested stream (wire-not-present), as opposed to a transient runtime failure. Used by Station::subscribe(set) to bucket per-stream outcomes in the returned SubscribeReport.

Trait Implementations

impl Debug for StationError

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

Formats the value using the given formatter.

impl Display for StationError

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

Formats the value using the given formatter.

impl Error for StationError

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.
