Enum syn::VariantData

pub enum VariantData {
    Struct(Vec<Field>),
    Tuple(Vec<Field>),
    Unit,
}

Data stored within an enum variant or struct.

Variants

Struct(Vec<Field>)

Struct variant, e.g. Point { x: f64, y: f64 }.

Tuple(Vec<Field>)

Tuple variant, e.g. Some(T).

Unit

Unit variant, e.g. None.

Methods

impl VariantData

pub fn fields(&self) -> &[Field]

Slice containing the fields stored in the variant.

pub fn fields_mut(&mut self) -> &mut [Field]

Mutable slice containing the fields stored in the variant.
