Struct BacktestDataConfig 

pub struct BacktestDataConfig { /* private fields */ }

Represents the data configuration for one specific backtest run.

Implementations

impl BacktestDataConfig

pub fn builder() -> BacktestDataConfigBuilder

Create an instance of BacktestDataConfig using the builder syntax

impl BacktestDataConfig

pub fn validate(&self) -> ConfigResult<()>

Validates the data configuration, collecting every field violation.

Errors

Returns a ConfigError (a ConfigError::Multiple when more than one field is invalid) if any field fails validation.

pub const fn data_type(&self) -> NautilusDataType

pub fn catalog_path(&self) -> &str

pub fn catalog_fs_protocol(&self) -> Option<&str>

pub fn catalog_fs_storage_options(&self) -> Option<&AHashMap<String, String>>

pub fn catalog_fs_rust_storage_options( &self, ) -> Option<&AHashMap<String, String>>

pub fn instrument_id(&self) -> Option<InstrumentId>

pub fn instrument_ids(&self) -> Option<&[InstrumentId]>

pub fn start_time(&self) -> Option<UnixNanos>

pub fn end_time(&self) -> Option<UnixNanos>

pub fn filter_expr(&self) -> Option<&str>

pub fn client_id(&self) -> Option<ClientId>

pub fn metadata(&self) -> Option<&AHashMap<String, String>>

pub fn bar_spec(&self) -> Option<BarSpecification>

pub fn bar_types(&self) -> Option<&[String]>

pub fn optimize_file_loading(&self) -> bool

pub fn query_identifiers(&self) -> Option<Vec<String>>

Constructs identifier strings for catalog queries.

Follows the same logic as Python’s BacktestDataConfig.query:

• For bars: prefer bar_types, else construct from instrument(s) + bar_spec + “-EXTERNAL”
• For other types: use instrument_id or instrument_ids

pub fn get_instrument_ids(&self) -> Result<Vec<InstrumentId>>

Returns all instrument IDs referenced by this config.

For bar_types, extracts the instrument ID from each bar type string.

Errors

Returns an error if any bar type string cannot be parsed.

Trait Implementations
