Struct BacktestDataIterator 

pub struct BacktestDataIterator { /* private fields */ }

Multi-stream, time-ordered data iterator used by the backtest engine.

Implementations

impl BacktestDataIterator

pub fn new() -> Self

Create an empty BacktestDataIterator.

pub fn add_data(&mut self, name: &str, data: Vec<Data>, append_data: bool)

Add (or replace) a named data stream. append_data=true gives the stream lower priority when timestamps tie, mirroring the original behaviour.

pub fn remove_data(&mut self, name: &str, complete_remove: bool)

Remove a stream. complete_remove also discards placeholder generator (not implemented yet).

pub fn set_index(&mut self, name: &str, index: usize)

Move cursor of stream to index (0-based).

pub fn next(&mut self) -> Option<Data>

Return next Data element across all streams in chronological order.

pub fn is_done(&self) -> bool
