pub struct PreparedQuery { /* private fields */ }Expand description
Scalar expressions compiled and prepared once for repeated batch evaluation. This object retains no event data and owns no cross-request compilation cache.
Implementations§
Source§impl PreparedQuery
impl PreparedQuery
Sourcepub fn prepare(
expressions: Vec<Expr>,
execution: &Execution,
require_real: bool,
) -> RuntimeResult<Self>
pub fn prepare( expressions: Vec<Expr>, execution: &Execution, require_real: bool, ) -> RuntimeResult<Self>
Compile scalar outputs in caller order for the selected backend.
Set require_real to reject complex outputs. Free parameters are rejected.
§Errors
Returns an error for invalid expressions or backend preparation failure.
Sourcepub fn evaluate_batch(
&self,
batch: &EventBatch,
) -> RuntimeResult<Vec<Vec<Complex64>>>
pub fn evaluate_batch( &self, batch: &EventBatch, ) -> RuntimeResult<Vec<Vec<Complex64>>>
Evaluate every output on a batch without retaining event values.
§Errors
Returns an error for incompatible event columns or failed evaluation.
