Struct impl_tools_lib::fields::Field

pub struct Field {
    pub attrs: Vec<Attribute>,
    pub vis: Visibility,
    pub ident: Option<Ident>,
    pub colon_token: Option<Colon>,
    pub ty: Type,
    pub assign: Option<(Eq, Expr)>,
}

A field of a struct or enum variant.

This is a variant of syn::Field supporting field initializers.

Fields

attrs: Vec<Attribute>

Attributes tagged on the field.

vis: Visibility

Visibility of the field.

ident: Option<Ident>

Name of the field, if any.

colon_token: Option<Colon>

: token before type

ty: Type

Type of the field.

assign: Option<(Eq, Expr)>

Optional field initializer.

This is considered legal input when parsing, but not legal output. An attribute rule such as crate::AttrImplDefault must remove the initializer before output is generated.

Implementations
