Struct ExprLit 

#[non_exhaustive]
pub struct ExprLit {
    pub attributes: Vec<Attribute>,
    pub lit: Lit,
}

A literal expression. With the addition of being able to receive attributes, this is identical to ast::Lit.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

Attributes associated with the literal expression.

lit: Lit

The literal in the expression.
