Type Alias: AssetFilter

type AssetFilter =
  | AssetPropertyFilter
  | {
  and: AssetFilter[];
  or?: never;
  not?: never;
  property?: never;
}
  | {
  or: AssetFilter[];
  and?: never;
  not?: never;
  property?: never;
}
  | {
  not: AssetFilter;
  and?: never;
  or?: never;
  property?: never;
};

Filter expression — predicate or logical combinator. Combinators nest arbitrarily. The union is mutually exclusive: an object with both and and or, or with property next to a combinator key, is rejected at the type level.

Missing-key semantics for not: a predicate is false on an asset that lacks the targeted field, so a negated meta.foo === 'x' matches assets where meta.foo !== 'x' and assets that lack meta.foo entirely.
