Struct syn::Constraint

pub struct Constraint {
    pub ident: Ident,
    pub colon_token: Colon,
    pub bounds: Punctuated<TypeParamBound, Add>,
}

An associated type bound: Iterator<Item: Display>.

This type is available if Syn is built with the "derive" or "full" feature.

Fields

ident: Ident

colon_token: Colon

bounds: Punctuated<TypeParamBound, Add>
