Expand description

Can either be extracted as a slice or a NullableSlice from an AnyColumnView. This allows the user to avoid matching on all possibile variants of an AnyColumnView in case the buffered type is known at compile time.

Associated Constants

E.g. BufferKind::I64 for i64. The kind can be used in a buffer description to instantiate a super::ColumnarBuffer.

Required methods

Extract the array type from an AnyColumnView.

Extract the typed nullable buffer from an AnyColumnView.

Extract the array type from an AnyColumnViewMut.

Extract the typed nullable buffer from an AnyColumnViewMut.
