Enum PartialOption

pub enum PartialOption<T: BasicOption> {
    Value(T),
    Partial(T::Partial, Error),
    None,
}

A field which may be partially parsed.

This is used for fields which may not be fully parseable, such as when handling autocomplete interactions.

Variants

Value(T)

A successfully parsed value.

Partial(T::Partial, Error)

A partially parsed value, along with the error that occurred while attempting to parse it.

None

A value that has not been entered yet.
