Enum OptionalRepr 

pub enum OptionalRepr {
    Hazzer,
    Option,
    None,
}

Representation of optional fields in the generated code

Variants

Hazzer

Presence of optional field is tracked in a separate bitfield called a hazzer.

Default for non-boxed fields.

Option

Optional field is wrapped in Option.

Default for boxed fields.

None

Represented as a non-optional field.

The field is represented the same way as with Hazzer, but without any presence tracking. Note that the presence of the field will always be on for the purpose of encoding and decoding, making it different from the implicit presence used by Proto3 non-optional fields. As such, accessors will always return Some, and the take_* and clear_* accessors won’t be generated.
