Enum FormatSpec 

pub enum FormatSpec {
    Named(Format),
    Pattern {
        pattern: String,
    },
}

format: as a step writes it: the name of a Format, or a pattern.

A pattern is a format too, one whose argument is the expression, so it is written under the same key rather than beside it.

Variants

Named(Format)

format: { pattern: "..." }

Fields

pattern: String

A regular expression the whole value must match.
