Enum RithmicError 

#[non_exhaustive]
pub enum RithmicError {
    ConnectionFailed(String),
    ConnectionClosed,
    SendFailed,
    EmptyResponse,
    ServerError(String),
}

Typed errors returned by all plant handle methods.

match handle.subscribe("ESH6", "CME").await {
    Ok(resp) => { /* success */ }
    Err(RithmicError::ConnectionClosed | RithmicError::SendFailed) => {
        handle.abort();
        // reconnect — see examples/reconnect.rs
    }
    Err(RithmicError::ServerError(msg)) => eprintln!("rejected: {msg}"),
    Err(e) => eprintln!("{e}"),
}

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.

ConnectionFailed(String)

WebSocket connection could not be established.

ConnectionClosed

The plant’s WebSocket connection is gone; pending requests will never complete.

SendFailed

WebSocket send failed after the request was registered.

EmptyResponse

Server returned an empty response where at least one was expected.

ServerError(String)

Protocol-level rejection from Rithmic (the rp_code text).

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

Formats the value using the given formatter.

impl Display for RithmicError

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

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>)
