Struct ComposedNode 

pub struct ComposedNode { /* private fields */ }

A GraphIndicator built from closures, for nodes that genuinely consume other nodes’ outputs (e.g. a Chandelier Exit reading an upstream ATR node).

Implementations

impl ComposedNode

pub fn new( name: impl Into<String>, dependencies: Vec<String>, warmup_period: usize, compute_fn: impl FnMut(&Bar, &HashMap<String, IndicatorOutput>) -> Option<IndicatorOutput> + Send + Sync + 'static, ) -> Self

pub fn with_reset(self, reset_fn: impl FnMut() + Send + Sync + 'static) -> Self

Registers a callback invoked on CompositionGraph::reset, for composed nodes that capture their own mutable state in the compute_fn closure.

Trait Implementations

impl GraphIndicator for ComposedNode

fn name(&self) -> &str

fn dependencies(&self) -> &[String]

Names of other graph nodes whose current-bar output this node reads via deps in GraphIndicator::compute. Must match node names actually present in the graph.

fn warmup_period(&self) -> usize

fn reset(&mut self)

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