LseExportRequest

rustrade_data::exchange::lse::export

Struct LseExportRequest 

Source 
pub struct LseExportRequest { /* private fields */ }
Expand description

A validated export request.

Construction is the validation step; see new. Holding one of these means the request is worth spending an export on, as far as anything checkable client-side goes.

Implementations§

Source§

impl LseExportRequest

Source

pub fn new( dataset: LseDataset, symbol: impl Into<String>, timeframe: LseExportTimeframe, range: LseExportRange, ) -> Result<Self, LseError>

Validate and build an export request.

§Why this validates so much

A rejected submit consumes one of five hourly exports. Every check here is a rejection the provider would otherwise bill for.

§Errors
  • LseError::InvalidInput if symbol is blank. Surrounding whitespace is trimmed before any check, so a padded symbol is neither smuggled past the "all" rejection below nor sent verbatim into a 400 that would cost an export.
  • LseError::InvalidInput if symbol is "all", on either timeframe — measured on both to produce a valid, empty artifact with no error (see the module documentation). The exact spelling "ALL" is admitted on Stocks and Etf only, where it is Allstate’s real ticker; on every other dataset a symbol is a pair or a contract slug, so no casing of it names anything.
  • LseError::InvalidInput if a candle resolution is requested for one of the provider’s synthetic classes. Those serve candles over REST but are tick-only on the export path — measured: {dataset: volatility, timeframe: 1d} → 400 … it is tick-only.
  • LseError::UnsupportedInterval for a resolution the provider does not serve.
