    pub visibility: Visibility,
    pub const_token: Const,
    pub name: Ident,
    pub eq: Eq,
    pub expr: Expr,
}

testing::roundtrip::<ast::ItemConst>("const value = #{}");

Fields

id: Option<Id>

Opaque identifier for the constant.

attributes: Vec<Attribute>

The inner attributes that are applied to the const declaration.

visibility: Visibility

The visibility of the const.

const_token: Const

The const keyword.

name: Ident

The name of the constant.

eq: Eq

The equals token.

expr: Expr

The optional body of the module declaration.

Implementations

impl ItemConst

pub fn parse_with_meta(
    parser: &mut Parser<'_>,

) -> Result<Self, ParseError>

Parse #ident and attach the given meta

impl ItemConst

pub fn descriptive_span(&self) -> Span
