Enum DecisionState 

pub enum DecisionState {
    Pending,
    Approved,
    Declined,
    Expired,
}

Where one decision record is in its life.

The whole state machine, in one place: a record is minted DecisionState::Pending at PAR and leaves that state exactly once — the named account approves it, the named account declines it, or its pushed request outlives its window and a sweep marks it DecisionState::Expired. There is no path back to Pending and no transition between the three terminal states. Only a Pending record is listed to an agent, and only a Pending record can be approved.

A record can also stop existing without reaching any of the three: the account’s newest push displaces its oldest undecided record when the account is at its bound (DecisionStore::put). A displaced record is removed rather than settled, so everything downstream sees exactly what it sees for one that expired and was swept.

Variants

Pending

Minted, and nobody has answered.

Approved

The named account approved it, and a code was issued.

Declined

The named account said no.

Expired

Nobody answered before the pushed request’s window closed.

Implementations

impl DecisionState

pub fn as_str(self) -> &'static str

The wire word for this state.

Trait Implementations

impl Clone for DecisionState

fn clone(&self) -> DecisionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecisionState

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

Formats the value using the given formatter.

impl PartialEq for DecisionState

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