Struct RunState 

pub struct RunState {
    pub statuses: BTreeMap<Symbol, NodeStatus>,
    pub counters: BTreeMap<Symbol, u64>,
    pub events: Vec<RunEvent>,
    pub live_edges: BTreeSet<(Symbol, Symbol)>,
}

The accumulated live state of a run.

Fields

statuses: BTreeMap<Symbol, NodeStatus>

Per-node status.

counters: BTreeMap<Symbol, u64>

Per-node event counter.

events: Vec<RunEvent>

Ordered event log.

live_edges: BTreeSet<(Symbol, Symbol)>

Currently live edges, by (from-node, to-node).

Implementations

impl RunState

pub fn new() -> Self

An empty run state.

pub fn apply_event(&mut self, event: RunEvent)

Fold one event into the state.

pub fn status(&self, node: &Symbol) -> NodeStatus

The status of a node (Idle if unseen).

pub fn count(&self, node: &Symbol) -> u64

The event count of a node.

pub fn edge_live(&self, from: &Symbol, to: &Symbol) -> bool

Whether an edge is currently live.

pub fn events_for(&self, node: &Symbol) -> Vec<&RunEvent>

The events that concern a node, in order (for drill-down).

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for RunState

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

impl Default for RunState

fn default() -> RunState

Returns the “default value” for a type.
