Struct Variant 

#[non_exhaustive]
pub struct Variant {
    pub name: String,
    pub type_params: Vec<String>,
    pub constructors: Vec<VariantConstructor>,
}

A variant (sum) type: named constructors, each optionally carrying a payload.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The type name (PascalCase).

type_params: Vec<String>

Type parameters, in order, if generic.

constructors: Vec<VariantConstructor>

The constructors, in declaration order.
