Struct TransitionRecord 

pub struct TransitionRecord<M, E, C> {
    pub step: usize,
    pub from: M,
    pub to: M,
    pub event: E,
    pub commands: Vec<C>,
    pub timestamp: SystemTime,
}

Available on crate feature journal only.

A record of one processed event.

A record captures the before/after modes and the emitted commands so a system can be audited or replayed deterministically.

Fields

step: usize

Sequential step index (0-based) within the journal.

from: M

Mode before processing the event.

to: M

Mode after applying the decision.

event: E

The processed event.

commands: Vec<C>

Commands emitted by the machine, in order.

timestamp: SystemTime

Timestamp recorded by the journal.

Implementations

impl<M, E, C> TransitionRecord<M, E, C>

pub fn new(step: usize, from: M, to: M, event: E, commands: Vec<C>) -> Self

Creates a new transition record.

Trait Implementations

impl<M: Clone, E: Clone, C: Clone> Clone for TransitionRecord<M, E, C>

fn clone(&self) -> TransitionRecord<M, E, C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug, E: Debug, C: Debug> Debug for TransitionRecord<M, E, C>

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

Formats the value using the given formatter.

impl<M: PartialEq, E: PartialEq, C: PartialEq> PartialEq for TransitionRecord<M, E, C>

fn eq(&self, other: &TransitionRecord<M, E, C>) -> 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.
