Struct Command 

pub struct Command {
    pub payload: CommandPayload,
    pub expires_after_tick: TickId,
    pub source_id: Option<u64>,
    pub source_seq: Option<u64>,
    pub priority_class: u8,
    pub arrival_seq: u64,
}

A command submitted to the simulation via the ingress pipeline.

Commands are ordered by priority_class (lower = higher priority), then by source_id for disambiguation, then by arrival_seq as a final tiebreaker.

Examples

use murk_core::{Command, CommandPayload, FieldId, TickId, ParameterKey};

// A command that sets a global parameter.
let cmd = Command {
    payload: CommandPayload::SetParameter {
        key: ParameterKey(0),
        value: 2.5,
    },
    expires_after_tick: TickId(100),
    source_id: Some(1),
    source_seq: Some(0),
    priority_class: 1,
    arrival_seq: 0,
};

assert_eq!(cmd.priority_class, 1);
assert_eq!(cmd.expires_after_tick, TickId(100));

Fields

payload: CommandPayload

The operation to perform.

expires_after_tick: TickId

The command expires if not applied by this tick.

source_id: Option<u64>

Optional source identifier for deduplication and ordering.

source_seq: Option<u64>

Optional per-source sequence number for ordering.

priority_class: u8

Priority class. Lower values = higher priority. 0 = system, 1 = user default.

arrival_seq: u64

Monotonic arrival sequence number, set by the ingress pipeline.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

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