Enum MfRange 

#[non_exhaustive]
pub enum MfRange {
    NameFirst {
        name: MfName,
        operator: MfComparison,
        value: MfValue,
    },
    ValueFirst {
        value: MfValue,
        operator: MfComparison,
        name: MfName,
    },
    Interval {
        lower: MfValue,

        name: MfName,

}

<mf-range>, all four grammar alternatives:

<mf-range> = <mf-name> <mf-comparison> <mf-value>
           | <mf-value> <mf-comparison> <mf-name>
           | <mf-value> <mf-lt> <mf-name> <mf-lt> <mf-value>
           | <mf-value> <mf-gt> <mf-name> <mf-gt> <mf-value>

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.

NameFirst

<mf-name> <mf-comparison> <mf-value>

Fields

name: MfName

The <mf-name> on the left.

operator: MfComparison

The comparison operator between name and value.

value: MfValue

The <mf-value> on the right.

ValueFirst

<mf-value> <mf-comparison> <mf-name>

Fields

value: MfValue

The <mf-value> on the left.

operator: MfComparison

The comparison operator between value and name.

name: MfName

The <mf-name> on the right.

Interval

<mf-value> <mf-lt> <mf-name> <mf-lt> <mf-value> | <mf-value> <mf-gt> <mf-name> <mf-gt> <mf-value>

One direction (<mf-lt> family or <mf-gt> family) for both operators, never a mixed form — the grammar itself only lists these two alternatives, no <mf-lt> ... <mf-gt> mix and no <mf-eq> in this position. Modeled with direction plus two separate inclusive flags rather than two independent MfComparison fields, so that a mixed form isn’t representable in the type at all.

Fields

lower: MfValue

The <mf-value> bound on the left.

lower_inclusive: bool

Whether the left operator is inclusive (<=/>=) rather than strict (</>).

name: MfName

The <mf-name> in the middle.

upper_inclusive: bool

Whether the right operator is inclusive (<=/>=) rather than strict (</>).

upper: MfValue

The <mf-value> bound on the right.

direction: MfRangeDirection

Which operator family (<mf-lt> or <mf-gt>) both sides use.
