Required Methods

fn new(name: String, desired_retention: f64) -> Self

fn get_name(&self) -> &str

fn get_desired_retention(&self) -> f64

fn set_desired_retention(&mut self, desired_retention: f64)

fn tasks_total(&self) -> usize

fn tasks_to_complete(&self) -> usize

fn complete_task( &mut self, interaction: &mut impl FnMut(TaskId, Blocks) -> Result<Response>, ) -> Result<(), Error>

If an error occurs, the tasks facade will remain unmodified.

Errors

If interaction return error.

fn insert(&mut self, task: T)

fn create_task(&mut self, input: BlocksWithAnswer)

fn iter<'t>(&'t self) -> impl Iterator<Item = (&'t T, TaskId)>

where T: 't,

Return itrator of (&task, id)

fn remove(&mut self, id: TaskId) -> bool

Remove task. Returns whether such an element was present.

fn optimize(&mut self) -> Result<(), Box<dyn Error>>

where T::SharedState: SharedStateExt<'a, T>,

Errors

If error occurs when optimizing. Guarantee to not modify anything.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
