Enum Extent 

#[non_exhaustive]
pub enum Extent {
    Values(Vec<String>),
    Range {
        lo: String,
        hi: String,
    },
}

The cells a slice over an argument enumerates (7, spec-0.4.0): the argument declaration’s optional extent.

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.

Values(Vec<String>)

Lexical values of the argument’s type, strictly ascending in the type’s order (numbers numerically, dates and instants chronologically, strings by code point); at most 4096.

Range

For a date or number argument, every date (or every integer) from lo to hi, inclusive; number ends are integers, and lo <= hi.

Fields

lo: String

The first value.

hi: String

The last value.
