Enum TraitItemKind 

pub enum TraitItemKind {
    Type(Vec<ImplIdent>),
    Fn(Ty),
    Default {
        params: Vec<Param>,
        body: Expr,
    },
    Resugared(ResugaredTraitItemKind),
    Error(ErrorNode),
}

Represents the kinds of trait items

Variants

Type(Vec<ImplIdent>)

An associated type

Fn(Ty)

An associated function

Default

An associated function with a default body. A arrow type (like what is given in TraitItemKind::Ty) can be reconstructed using the types of the parameters and of the body.

Example:

impl ... {
  fn f(x: u8) -> u8 { x + 2 }
}

Fields

params: Vec<Param>

The parameters of the associated function ([x: u8] in the example).

body: Expr

The default body of the associated function (x + 2 in the example).

Resugared(ResugaredTraitItemKind)

A resugared trait item. This variant is introduced before printing only. Phases must not produce this variant.

Error(ErrorNode)

Fallback constructor to carry errors.
