Enum PostError 

#[non_exhaustive]
pub enum PostError {
    Full,
    WrongWorker,
    ServerStopped,
}

Why a post was refused.

assert_eq!(net_io::PostError::Full.to_string(), "the worker's completion queue is full");

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.

Full

The ring is full; the poster decides what to do (for example answer 503).

WrongWorker

The connection belongs to another worker.

ServerStopped

The server has stopped.

impl Eq for PostError

impl Error for PostError

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.
