    // Required methods
    fn name(&self) -> &str;
    fn dependencies(&self) -> &[String];

Expand description

A node in a CompositionGraph. Unlike Indicator, compute also receives the current bar’s already-computed outputs of this node’s declared GraphIndicator::dependencies.

Required Methods§

Source

fn name(&self) -> &str

Source

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.
