Enum MediaQuery 

#[non_exhaustive]
pub enum MediaQuery {
    Condition(MediaCondition),
    TypeQuery {
        modifier: Option<MediaModifier>,
        media_type: MediaType,
        condition: Option<MediaConditionWithoutOr>,
    },
}

<media-query> = <media-condition> | [ not | only ]? <media-type> [ and <media-condition-without-or> ]?

Modeled as an enum rather than a single struct with optional fields: the two grammar branches allow structurally different condition kinds (a full <media-condition> with or only in the first branch, <media-condition-without-or> only in the second), which an enum expresses type-safely.

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.

Condition(MediaCondition)

The bare <media-condition> branch.

TypeQuery

The [ not | only ]? <media-type> [ and <media-condition-without-or> ]? branch.

Fields

modifier: Option<MediaModifier>

The optional not/only prefix, if present.

media_type: MediaType

The <media-type> itself.

condition: Option<MediaConditionWithoutOr>

The optional and <media-condition-without-or> suffix.
