Enum DrainAction 

pub enum DrainAction {
    Sent,
    Discard,
    Stop,
}

What a drain_outbox / drain_pubrel visitor decides for the entry it was handed.

Variants

Sent

The entry was put on the wire: mark it in-flight for this connection (so it is not re-sent until the next reconnect) and, for outbox entries, record that it has been sent at least once (DUP on resend).

Discard

The entry could not be sent and must be dropped from the session.

Stop

Stop draining now (e.g. the send quota is exhausted); leave this entry and all not-yet-visited entries untouched.

impl Clone for DrainAction

fn clone(&self) -> DrainAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DrainAction

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

Formats the value using the given formatter.

impl PartialEq for DrainAction

fn eq(&self, other: &DrainAction) -> 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.
