Enum rustc_error_messages::FluentValue

pub enum FluentValue<'source> {
    String(Cow<'source, str>),
    Number(FluentNumber),
    Custom(Box<dyn FluentType + Send>),
    None,
    Error,
}

The FluentValue enum represents values which can be formatted to a String.

Those values are either passed as arguments to FluentBundle::format_pattern or produced by functions, or generated in the process of pattern resolution.

Variants

String(Cow<'source, str>)

Number(FluentNumber)

Custom(Box<dyn FluentType + Send>)

None

Error

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
