Enum FallbackSource 

#[non_exhaustive]
pub enum FallbackSource<'p> {
    Variable(&'p str),
    Literal(&'p str),
    Function(&'p str),
    Unknown,
}

What a fallback value shows (formatting.md, “Fallback Resolution”).

Variants (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.

Variable(&'p str)

$name.

Literal(&'p str)

|value|, with \ and | escaped.

Function(&'p str)

:ns:name.

Unknown

� (a malformed record, or a name that could not be read).
