pub fn eval(
expr: &CompiledExpr,
args: HashMap<&str, EvalInput>,
) -> Result<EvalHandle, EvalError>Expand description
Create a lazy eval handle from a compiled expression and arguments.
Validates that all expected arguments are provided and no unknown
arguments are present. Resolves inputs and computes output shape,
but defers evaluation until consumed via scalar(), to_array(),
or iter().
