Implementations

impl CompiledIndicator

pub fn warmup_bars(&self, config: &IndicatorConfig) -> Option<usize>

Static bars of history the plotted values need before they are meaningful, resolved from constants, inputs, and windowed intrinsics. Returns None when history analysis exceeds its limits.

pub fn warmup_bars_with_limits( &self, config: &IndicatorConfig, limits: RuntimeLimits, ) -> Option<usize>

Resolve warmup using the same rolling-window policy as the runtime.

pub fn anchor_start( &self, config: &IndicatorConfig, reference_time: i64, ) -> Option<i64>

Earliest UTC boundary an anchored intrinsic needs data from, resolved from the configuration. Returns None when the indicator has no anchored calculations such as ta.avwap, or when analysis exceeds its limits.

pub fn validate_history_analysis( &self, config: &IndicatorConfig, ) -> Result<(), PlanningError>

Reject configurations whose history analysis exceeds its work or depth limits.

pub fn requires_anchored_history(&self) -> bool

Whether the compiled program contains calculations requiring complete anchor history.

pub fn instantiate( &self, config: IndicatorConfig, ) -> Result<IndicatorInstance, PlanningError>

Create an instance that evaluates only the frames supplied by the chart.

pub fn instantiate_with_limits( &self, config: IndicatorConfig, limits: RuntimeLimits, ) -> Result<IndicatorInstance, PlanningError>
