Macros
The binary_array_op macro includes types that extend beyond the primitive,
such as Utf8 strings.
The binary_array_op_dyn_scalar macro includes types that extend
beyond the primitive, such as Utf8 strings.
Structs
The shared context used during the analysis of an expression. Includes
the boundaries for all known columns.
Represents the boundaries of the resulting value from a physical expression,
if it were to be an expression, if it were to be evaluated.
Represents Sort operation for a column in a RecordBatch
Physical expression of a scalar function
Traits
Expression that can be evaluated against a RecordBatch
A Physical expression knows its type, nullability and how to evaluate itself.
