Struct WorkRequestError 

pub struct WorkRequestError {
    pub wr_id: u64,
    pub status: Type,
    pub vendor_err: u32,
    /* private fields */
}

A per-work-request completion failure: a work request completed with a non-success ibv_wc_status. Carries the wr_id, status, and vendor error code so callers can correlate the failure to the request and match on the status without string parsing. The QP may or may not be in error state.

Fields

wr_id: u64

status: Type

vendor_err: u32

Implementations

impl WorkRequestError

pub fn is_wr_flush_err(&self) -> bool

Returns true when the completion status is IBV_WC_WR_FLUSH_ERR, which typically indicates a secondary failure after the QP entered error state due to a different work request’s failure.

Trait Implementations

impl Debug for WorkRequestError

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

Formats the value using the given formatter.

impl Display for WorkRequestError

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

Formats the value using the given formatter.

impl Error for WorkRequestError

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>)
