Implementations

impl IndicatorInstanceStore

pub fn validate_source_binding( &self, active: &[IndicatorInstanceId], id: IndicatorInstanceId, input_id: &str, ) -> Result<(), String>

pub fn source_offsets(&self) -> Vec<i64>

pub fn max_positive_output_offset(&self) -> i64

pub fn from_instances(instances: Vec<IndicatorInstance>) -> Self

pub fn instances(&self) -> &[IndicatorInstance]

pub fn get(&self, id: IndicatorInstanceId) -> Option<&IndicatorInstance>

pub fn warmup_bars(&self, id: IndicatorInstanceId) -> Option<u64>

pub fn create(&mut self, kind: IndicatorId) -> IndicatorInstanceId

pub fn update_config( &mut self, id: IndicatorInstanceId, config: IndicatorConfig, ) -> bool

pub fn reset_config(&mut self, id: IndicatorInstanceId) -> bool

pub fn update_source_binding( &mut self, id: IndicatorInstanceId, input_id: impl Into<String>, output: Option<IndicatorOutputRef>, ) -> bool

pub fn update_base_source( &mut self, id: IndicatorInstanceId, input_id: impl Into<String>, source: Option<BaseSeriesSource>, ) -> bool

pub fn update_color( &mut self, id: IndicatorInstanceId, slot: impl Into<String>, color: ThemeColor, ) -> bool

pub fn update_fill_visibility( &mut self, id: IndicatorInstanceId, visible: bool, ) -> bool

pub fn update_line_width( &mut self, id: IndicatorInstanceId, slot: impl Into<String>, width: u8, ) -> bool

pub fn update_stroke_style( &mut self, id: IndicatorInstanceId, slot: impl Into<String>, stroke_style: LineStrokeStyle, ) -> bool

pub fn reset_style(&mut self, id: IndicatorInstanceId) -> bool

pub fn remove(&mut self, id: IndicatorInstanceId) -> Option<IndicatorInstance>

pub fn history_requirement( &self, active: &[IndicatorInstanceId], basis: Basis, reference_time: UnixMs, ) -> IndicatorHistoryRequirement

impl IndicatorInstanceStore

pub fn dependency_target<'a>( &'a self, instance: &IndicatorInstance, source_id: &str, active: &BTreeSet<IndicatorInstanceId>, ) -> Result<Option<&'a IndicatorInstance>, SourceBindingProblem>

Resolves source_id on instance to the instance it draws from.

Ok(None) means the binding is absent, so the input contributes nothing. Err means the binding is present but cannot act as a dependency.

pub fn dependency_edges( &self, active: &BTreeSet<IndicatorInstanceId>, excluded: Option<(IndicatorInstanceId, &str)>, ) -> BTreeMap<IndicatorInstanceId, Vec<IndicatorInstanceId>>

Dependency edges among active instances, optionally ignoring one binding.
