Enum Outcome 

pub enum Outcome {
    Request,
    Reply,
    Timeout,
    PeerLost,
    QueueFull,
    Aborted,
    Unknown,
}

How an exchange ENDED. One row per exchange, so this is its whole story.

Variants

Request

A request went out.

Reply

A reply came back. The exchange closed normally.

Timeout

No reply before the deadline. The outcome is unknown - it may still have happened.

PeerLost

The peer died while the exchange was open.

QueueFull

The peer’s queue was full, so the request never left. Nothing happened.

Aborted

The user changed their mind. Not a failure.

Unknown

A kind this library does not know. Newer sink than stdlib, or a corrupt row.

Implementations

impl Outcome

pub fn is_failure(self) -> bool

Did the exchange fail to get where it was going?

True for Outcome::Timeout, Outcome::PeerLost and Outcome::QueueFull. False for Outcome::Aborted, which is a person deciding, not a fault - counting it as one turns every impatient keypress into a reliability statistic.

Trait Implementations

impl Clone for Outcome

fn clone(&self) -> Outcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Outcome

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

impl PartialEq for Outcome

fn eq(&self, other: &Outcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
