Implementations

impl DeliveryState

pub const fn of_step(step: DeliveryStep) -> DeliveryState

The state a transport’s step means here.

pub const fn key(self) -> &'static str

The catalogue key for this state’s word, in the desktop’s language.

pub fn label(self) -> String

The state’s word, in the desktop’s language.

pub const fn icon(self) -> Icon

The glyph this state carries: a clock while it is on its way, a tick once a transport has it, a circle-check once the other person’s device has it — and a warning where the answer is a refusal or a silence. A step within a stage (Submitted and Sent, Delivered and Read) is told by its word; the glyph tells the stage, which is what a glance reads.

pub const fn tone(self) -> Tone

The tone the state reads in. Progress is quiet — it is a fact about a message, not a call on the person’s attention — while a refusal and an unknown are the two states that need them.

pub const fn rank(self) -> u8

How far along the one progression this state stands. A later state never replaces an earlier one, so a stale Delivered cannot walk a line back to Sending.

pub const fn is_final(self) -> bool

Whether this is the last thing the transport will say about a line.

pub const fn needs_attention(self) -> bool

Whether the state asks for the person’s attention (a refusal, or an answer the transport could not give).

pub fn then(self, later: DeliveryState) -> DeliveryState

The state a line on self should show, given that later was just reported: the later one, unless it would move a final state backwards.

Trait Implementations

impl Clone for DeliveryState

fn clone(&self) -> DeliveryState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeliveryState

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

Formats the value using the given formatter.

impl PartialEq for DeliveryState

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

impl PropType for DeliveryState

fn ty() -> Type

fn from_value(value: &Value) -> Result<DeliveryState, String>

Errors

fn read(value: &Value, source: &mut dyn Source) -> Result<Self, String>

The value as the instance source gives it: what it reads beside the value itself (the event an offered action fires) is the instance’s.
