# Enum rustc_errors::DiagnosticArgValue

source ·

    pub enum DiagnosticArgValue<'source> {
        Str(Cow<'source, str>),
        Number(i128),
        StrListSepByAnd(Vec<Cow<'source, str>>),
    }

Expand description

Simplified version of `FluentValue` that can implement `Encodable` and `Decodable`. Converted to a `FluentValue` by the emitter to be used in diagnostic translation.
