Expand description

wasmbus.contractId: wasmcloud:keyvalue wasmbus.providerReceive

Required Methods

Increments a numeric value, returning the new value

returns whether the store contains the key

Deletes a key, returning true if the key was deleted

Gets a value for a specified key. If the key exists, the return structure contains exists: true and the value, otherwise the return structure contains exists == false.

Append a value onto the end of a list. Returns the new list size

Deletes a list and its contents input: list name output: true if the list existed and was deleted

Deletes a value from a list. Returns true if the item was removed.

Retrieves a range of values from a list using 0-based indices. Start and end values are inclusive, for example, (0,10) returns 11 items if the list contains at least 11 items. If the stop value is beyond the end of the list, it is treated as the end of the list.

Sets the value of a key. expires is an optional number of seconds before the value should be automatically deleted, or 0 for no expiration.

Add an item into a set. Returns number of items added (1 or 0)

Deletes an item from the set. Returns number of items removed from the set (1 or 0)

perform intersection of sets and returns values from the intersection. input: list of sets for performing intersection (at least two) output: values

Retrieves all items from a set input: String output: set members

perform union of sets and returns values from the union input: list of sets for performing union (at least two) output: union of values

clears all values from the set and removes it input: set name output: true if the set existed and was deleted

Provided Methods

returns the capability contract id for this interface
