Enum SdoResult 

pub enum SdoResult {
    Pending,
    Ok(Value),
    Err(String),
    Timeout,
}

Result of checking an in-flight SDO request.

Returned by SdoClient::result(). The caller should match on this each tick until the request resolves (i.e. is no longer Pending).

match sdo.result(ctx.client, tid, Duration::from_secs(3)) {
    SdoResult::Pending => { /* check again next tick */ }
    SdoResult::Ok(data) => { /* use data */ }
    SdoResult::Err(msg) => { log::error!("{}", msg); }
    SdoResult::Timeout => { log::error!("timed out"); }
}

Variants

Pending

No response yet; check again next tick.

Ok(Value)

Operation succeeded. Contains the response data field — the read value for reads, or an empty/null value for writes.

Err(String)

The server (or EtherCAT master) reported an error. The string contains the error_message from the response (e.g. "SDO abort: 0x06090011").

Timeout

No response arrived within the caller-specified deadline.
