Enum ExprLit

Source 
#[non_exhaustive]
pub enum ExprLit {
    Int(IntLit),
    String(StringLit),
    Bool(BoolLit),
    Null(NullLit),
}
Expand description

A literal inside an expression

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Int(IntLit)

An integer literal, see IntLit

§

String(StringLit)

A string literal, see StringLit

§

Bool(BoolLit)

A boolean literal, see BoolLit

§

Null(NullLit)

A null literal, see NullLit
