pub enum Data<V, F> {
    Enum(Vec<V>),
    Struct(Fields<F>),
}
Expand description

A struct or enum body.

V is the type which receives any encountered variants, and F receives struct fields.

Variants

Enum(Vec<V>)

Struct(Fields<F>)

Implementations

Creates an empty body of the same shape as the passed-in body.

Creates a new Data<&'a V, &'a F> instance from Data<V, F>.

Applies a function V -> U on enum variants, if this is an enum.

Applies a function F -> U on struct fields, if this is a struct.

Applies a function to the Fields if this is a struct.

Consumes the Data, returning Fields<F> if it was a struct.

Consumes the Data, returning Vec<V> if it was an enum.

Returns true if this instance is Data::Enum.

Returns true if this instance is Data::Struct.

Attempt to convert from a syn::Data instance.
