Bucket | |
PrefixedStorage | |
ReadonlyBucket | |
ReadonlyPrefixedStorage | |
ReadonlySingleton | ReadonlySingleton only requires a Storage and exposes only the methods of Singleton that don't modify state. |
Singleton | Singleton effectively combines PrefixedStorage with TypedStorage to work on a single storage key. It performs the to_length_prefixed transformation on the given name to ensure no collisions, and then provides the standard TypedStorage accessors, without requiring a key (which is defined in the constructor) |
Functions
bucket | An alias of Bucket::new for less verbose usage |
bucket_read | An alias of ReadonlyBucket::new for less verbose usage |
currval | currval returns the last value returned by nextval. If the sequence has never been used, then it will return 0. |
nextval | nextval increments the counter by 1 and returns the new value. On the first time it is called (no sequence info in db) it will return 1. |
prefixed | An alias of PrefixedStorage::new for less verbose usage |
prefixed_read | An alias of ReadonlyPrefixedStorage::new for less verbose usage |
sequence | Sequence creates a custom Singleton to hold an empty sequence |
singleton | An alias of Singleton::new for less verbose usage |
singleton_read | An alias of ReadonlySingleton::new for less verbose usage |
to_length_prefixed | Calculates the raw key prefix for a given namespace as documented in https://github.com/webmaster128/key-namespacing#length-prefixed-keys |
to_length_prefixed_nested | Calculates the raw key prefix for a given nested namespace as documented in https://github.com/webmaster128/key-namespacing#nesting |
