pub fn named<T>(&mut self, name: impl ToString, ty: T) -> &mut Self

where T: Into<Type>,

Add a named field to the variant.

An enum variant can either set named fields with this function or tuple fields with tuple, but not both.

pub fn new_named<T>(&mut self, name: impl ToString, ty: T) -> &mut Field

where T: Into<Type>,

Create a named field for the enum.

An enum variant can either set named fields with this function or tuple fields with tuple, but not both.

pub fn tuple(&mut self, ty: impl ToString) -> &mut Self

An enum variant can either be a tuple with this function or have named fields with named, but not both.

pub fn doc(&mut self, documentation: impl ToString) -> &mut Self

Set the variant documentation.

pub fn annotation(&mut self, annotation: impl Into<String>) -> &mut Self

Add an anotation to the variant.

pub fn discriminant(&mut self, discriminant: impl ToString) -> &mut Self

Set the discriminant value for the variant.

pub fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the variant using the given formatter.
