Type Alias rustc_builtin_macros::util::UnexpectedExprKind

type UnexpectedExprKind<'a> = Result<(Diag<'a>, bool), ErrorGuaranteed>;

• Ok is returned when the conversion to a string literal is unsuccessful, but another type of expression is obtained instead.
• Err is returned when the conversion process fails.

Aliased Type

enum UnexpectedExprKind<'a> {
    Ok((Diag<'a>, bool)),
    Err(ErrorGuaranteed),
}

Variants

Contains the success value

Err(ErrorGuaranteed)

Contains the error value
