Expand description

Commands for a key-value store.

Variants§

§

Set(SetCommand)

Set a key/value pair.

§

Get

Fields

§delete: bool

Remove the key after retrieving the value.

Get the value from a key.

§

Increment

Fields

§amount: Numeric

The amount to increment by.

§saturating: bool

If true, the result will be constrained to the numerical bounds of the type of amount.

Increment a numeric key. Returns an error if the key cannot be deserialized to the same numeric type as amount. If saturating is true, overflows will be prevented and the value will remain within the numeric bounds.

§

Decrement

Fields

§amount: Numeric

The amount to increment by.

§saturating: bool

If true, the result will be constrained to the numerical bounds of the type of amount.

Decrement a numeric key. Returns an error if the key cannot be deserialized to the same numeric type as amount. If saturating is true, overflows will be prevented and the value will remain within the numeric bounds.

§

Delete

Delete a key.
