Enum DeliveryStep 

pub enum DeliveryStep {
    Queued,
    Sending,
    Submitted,
    Acknowledged,
    Delivered,
    Read,
    Refused,
    Uncertain,
}

What a transport reported, before this toolkit decides how to say it.

A transport’s own enum maps onto this one by renaming its variants; nothing is inferred and no step is skipped. Where a transport reports nothing at all, there is no step and no state — an empty delivery line, not a guess.

Variants

Queued

Written here, waiting for this device to send it.

Sending

In flight: the transport has it and is working.

Submitted

Handed to the transport, which has not yet answered.

Acknowledged

The transport’s server acknowledged it.

Delivered

The other person’s device has it.

Read

The other person has read it.

Refused

The transport refused it.

Uncertain

The transport could not say whether it arrived.

Trait Implementations

impl Clone for DeliveryStep

fn clone(&self) -> DeliveryStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeliveryStep

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

Formats the value using the given formatter.

impl PartialEq for DeliveryStep

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