Enum syn::TypeParamBound

#[non_exhaustive]
pub enum TypeParamBound {
    Trait(TraitBound),
    Lifetime(Lifetime),
    PreciseCapture(PreciseCapture),
    Verbatim(TokenStream),
}

A trait or lifetime used as a bound on a type parameter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
