Struct ResourceManager 

pub struct ResourceManager { /* private fields */ }

Manages the concrete resources available to tasks and bridges.

Implementations

impl ResourceManager

pub fn new(num_resources: usize) -> ResourceManager

Creates a new manager sized for the number of resources generated for the current mission.

pub fn add_owned<T>( &mut self, key: ResourceKey<T>, value: T, ) -> Result<(), CuError>

where T: 'static + Send + Sync,

Register an owned resource in the slot identified by key.

pub fn add_shared<T>( &mut self, key: ResourceKey<T>, value: Arc<T>, ) -> Result<(), CuError>

where T: 'static + Send + Sync,

Register a shared (borrowed) resource. Callers keep an Arc while tasks receive references.

pub fn borrow<'r, T>( &'r self, key: ResourceKey<T>, ) -> Result<Borrowed<'r, T>, CuError>

where T: 'static + Send + Sync,

Borrow a shared resource by key.

pub fn borrow_shared_arc<T>( &self, key: ResourceKey<T>, ) -> Result<Arc<T>, CuError>

where T: 'static + Send + Sync,

Borrow a shared Arc-backed resource by key, cloning the Arc for the caller.

pub fn take<T>(&mut self, key: ResourceKey<T>) -> Result<Owned<T>, CuError>

where T: 'static + Send + Sync,

Move out an owned resource by key.

pub fn add_bundle_prebuilt( &mut self, builder: impl FnOnce(&mut ResourceManager) -> Result<(), CuError>, ) -> Result<(), CuError>

Insert a prebuilt bundle by running a caller-supplied function. This is the escape hatch for resources that must be constructed in application code (for example, owning handles to embedded peripherals).
