Struct PollCompletionError 

pub struct PollCompletionError {
    pub status: Option<Type>,
    pub vendor_err: Option<u32>,
    /* private fields */
}

A structured error from IbvQueuePair::poll_completion.

Carries the ibv_wc_status and vendor error code (when available) so callers can match on specific completion statuses without string parsing.

Fields

status: Option<Type>

vendor_err: Option<u32>

Implementations

impl PollCompletionError

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

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>)
