An Operation defines a single change to the task database

Variants

Create

On application, if the task already exists, the operation does nothing.

Fields of Create

uuid: Uuid

Delete

Delete an existing task.

On application, if the task does not exist, the operation does nothing.

Fields of Delete

uuid: Uuid

Update

Update an existing task, setting the given property to the given value. If the value is None, then the corresponding property is deleted.

If the given task does not exist, the operation does nothing.

Fields of Update

uuid: Uuidproperty: Stringvalue: Option<String>timestamp: DateTime<Utc>
