Struct TriggerTable 

pub struct TriggerTable<S: State> {
    pub outgoing: HashMap<String, Vec<CompiledEdge<S>>>,
    pub incoming: HashMap<String, Vec<TriggerSource>>,
}

Trigger table for compiled graph execution

Maps nodes to their outgoing edges (which nodes they trigger) and incoming edges (what triggers them).

Examples

use juncture_core::edge::{TriggerTable, CompiledEdge, TriggerSource};
use std::collections::HashMap;

let mut trigger_table = TriggerTable::<MyState>::new();
trigger_table.outgoing.insert(
    "node_a".to_string(),
    vec![CompiledEdge::Fixed { target: "node_b".to_string() }],
);

Fields

outgoing: HashMap<String, Vec<CompiledEdge<S>>>

Map of node name to its outgoing edges

incoming: HashMap<String, Vec<TriggerSource>>

Map of node name to sources that trigger it

Implementations

impl<S: State> TriggerTable<S>

pub fn new() -> Self

Create a new empty trigger table

pub fn add_outgoing(&mut self, from: String, edge: CompiledEdge<S>)

Add an outgoing edge for a node

pub fn add_incoming(&mut self, to: String, source: TriggerSource)

Add an incoming trigger for a node

pub fn sources(&self) -> impl Iterator<Item = &String>

Get all nodes that have outgoing edges

pub fn targets(&self) -> impl Iterator<Item = &String>

Get all nodes that have incoming edges
