Struct TaskRegistry 

pub struct TaskRegistry { /* private fields */ }

Registry of tasks discovered via inventory (auto_discover) or register. Prefer BosonBuilder::auto_registry at boot.

Implementations

impl TaskRegistry

pub fn get_or_err( &self, name: &str, ) -> Result<&'static TaskDescriptor, BosonError>

Look up a task by name, returning an error if not found.

Errors

Returns BosonError::TaskNotFound when the name is absent.

pub fn sorted_task_names(&self) -> Vec<&str>

Task names in sorted order.

impl TaskRegistry

pub fn new() -> TaskRegistry

pub fn auto_discover() -> TaskRegistry

pub fn register(&mut self, item: &'static TaskDescriptor)

Methods from Deref<Target = Registry<TaskDescriptor>>

pub fn register(&mut self, item: &'static T)

Insert a descriptor. If a descriptor with the same key already exists, it is replaced (last-write-wins).

pub fn get(&self, key: &str) -> Option<&'static T>

Look up an item by registry key.

pub fn list(&self) -> Vec<&str>

Returns all registered keys in arbitrary order.

pub fn len(&self) -> usize

Return the number of registered items.

pub fn is_empty(&self) -> bool

Return true when no items are registered.

pub fn iter(&self) -> impl Iterator<Item = &'static T>

Iterates over all registered descriptors in arbitrary order.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TaskRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Returns the “default value” for a type.

impl Deref for TaskRegistry

type Target = Registry<TaskDescriptor>

The resulting type after dereferencing.

fn deref(&self) -> &<TaskRegistry as Deref>::Target

Dereferences the value.
