Enum MetadataFilter 

#[non_exhaustive]
pub enum MetadataFilter {
    All,
    Exists(String),
    Equal {
        field: String,
        value: MetadataValue,

    And(Vec<Self>),
    Or(Vec<Self>),
    Not(Box<Self>),
}

Composable deterministic predicate over vector metadata.

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.
