Enum FirestoreDbSessionCacheMode 

pub enum FirestoreDbSessionCacheMode {
    None,
    ReadThroughCache(FirestoreSharedCacheBackend),
    ReadCachedOnly(FirestoreSharedCacheBackend),
}

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. Defines the caching mode for Firestore operations within a session.

This enum is used in FirestoreDbSessionParams to control how and if caching is utilized for read operations.

Variants

None

No caching is performed. All read operations go directly to Firestore.

ReadThroughCache(FirestoreSharedCacheBackend)

Enables read-through caching.

When a read operation is performed:

1. The cache is checked first.
2. If data is found in the cache, it’s returned.
3. If data is not in the cache, it’s fetched from Firestore, stored in the cache, and then returned.

This mode is only available if the caching feature is enabled.

ReadCachedOnly(FirestoreSharedCacheBackend)

Reads exclusively from the cache.

When a read operation is performed:

1. The cache is checked.
2. If data is found, it’s returned.
3. If data is not found, the operation will typically result in a “not found” status without attempting to fetch from Firestore.

This mode is only available if the caching feature is enabled.
