Structs
| Bucket | |
| PrefixedStorage | |
| ReadonlyBucket | |
| ReadonlyPrefixedStorage | |
| ReadonlySingleton | ReadonlySingleton only requires a ReadonlyStorage and exposes only the methods of Singleton that don't modify state. |
| ReadonlyTypedStorage | |
| SeqVal | SeqVal holds a u64 sequence counter but wraps it as a newtype for clarity but mainly to be able to derive NamedType. If named_type included a default derivation for u64 and other primitives, we could just use a u64 here. |
| Singleton | Singleton effectively combines PrefixedStorage with TypedStorage to work on one single value. It performs the key_prefix 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) |
| TypedStorage |
Functions
| bucket | |
| bucket_read | |
| currval | currval returns the last value returned by nextval. If the sequence has never been used, then it will return 0. |
| deserialize | |
| 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 | |
| prefixed_read | |
| sequence | Sequence creates a custom Singleton to hold an empty sequence |
| serialize | serialize makes json bytes, but returns a cosmwasm::Error |
| singleton | |
| singleton_read | |
| typed | |
| typed_read |
