Enum FirestoreQueryFilter 

pub enum FirestoreQueryFilter {
    Composite(FirestoreQueryFilterComposite),
    Unary(FirestoreQueryFilterUnary),
    Compare(Option<FirestoreQueryFilterCompare>),
}

Re-exports all public items from the db module.

The db module contains the core FirestoreDb client and functionalities for interacting with the Firestore database, such as CRUD operations, queries, and transactions. Represents a filter condition for a Firestore query.

Filters are used to narrow down the documents returned by a query based on conditions applied to their fields.

Variants

Composite(FirestoreQueryFilterComposite)

A composite filter that combines multiple sub-filters using an operator (AND/OR).

Unary(FirestoreQueryFilterUnary)

A unary filter that applies an operation to a single field (e.g., IS NULL, IS NAN).

Compare(Option<FirestoreQueryFilterCompare>)

A field filter that compares a field to a value (e.g., equality, greater than). The Option allows for representing an effectively empty or no-op filter, which can be useful in dynamic filter construction.
