Struct CompositionGraph 

pub struct CompositionGraph { /* private fields */ }

A dependency-ordered set of GraphIndicator nodes, executed together per bar.

Implementations

impl CompositionGraph

pub fn build(nodes: Vec<Box<dyn GraphIndicator>>) -> Result<Self, GraphError>

Builds a graph from nodes, computing a topological execution order and each node’s effective warmup (its own warmup_period plus the maximum effective warmup of its dependencies). Fails on duplicate node names, references to unknown dependencies, or a dependency cycle.

pub fn order(&self) -> &[String]

Execution order computed at CompositionGraph::build time (dependencies before dependents).

pub fn effective_warmup(&self, name: &str) -> Option<usize>

A node’s effective warmup: its own warmup plus the maximum effective warmup among its dependencies.

pub fn on_bar(&mut self, bar: &Bar) -> HashMap<String, Option<IndicatorOutput>>

Runs one bar through every node in dependency order, making each node’s output available to its dependents within the same call. Returns every node’s output for this bar.

pub fn reset(&mut self)
