type alias Deno.KvMutation
Unstable
A mutation to a key in a [`Deno.Kv`](../././~/Deno.Kv). A mutation is a
combination of a key, a value, and a type. The type determines how the
mutation is applied to the key.
- `set` - Sets the value of the key to the given value, overwriting any
existing value. Optionally an `expireIn` option can be specified to
set a time-to-live (TTL) for the key. The TTL is specified in
milliseconds, and the key will be deleted from the database at earliest
after the specified number of milliseconds have elapsed. Once the
specified duration has passed, the key may still be visible for some
additional time. If the `expireIn` option is not specified, the key will
not expire.
- `delete` - Deletes the key from the database. The mutation is a no-op if
the key does not exist.
- `sum` - Adds the given value to the existing value of the key. Both the
value specified in the mutation, and any existing value must be of type
`Deno.KvU64`. If the key does not exist, the value is set to the given
value (summed with 0). If the result of the sum overflows an unsigned
64-bit integer, the result is wrapped around.
- `max` - Sets the value of the key to the maximum of the existing value
and the given value. Both the value specified in the mutation, and any
existing value must be of type `Deno.KvU64`. If the key does not exist,
the value is set to the given value.
- `min` - Sets the value of the key to the minimum of the existing value
and the given value. Both the value specified in the mutation, and any
existing value must be of type `Deno.KvU64`. If the key does not exist,
the value is set to the given value.
