Struct BundleRegistry 

pub struct BundleRegistry { /* private fields */ }

Holds bundles until the kernel compiles them.

Registration order is preserved when there are no dependencies; otherwise Self::sorted returns a topologically sorted list (dependencies first).

Implementations

impl BundleRegistry

pub fn new() -> Self

Empty registry.

pub fn register( &mut self, bundle: impl BundleInterface + 'static, ) -> Result<(), KernelError>

Registers a bundle. Names must be unique.

Errors

Returns KernelError::DuplicateBundle when bundle.name() is already present.

pub fn names(&self) -> Vec<&'static str>

Registered names in registration order (before sorting).

pub fn len(&self) -> usize

Number of registered bundles.

pub fn is_empty(&self) -> bool

Whether no bundles are registered.

pub fn sorted(self) -> Result<Vec<Box<dyn BundleInterface>>, KernelError>

Returns bundles in dependency order (dependencies before dependents).

Among ready nodes, lower registration index wins (stable).

Errors

• KernelError::UnknownBundleDependency when a dependency was never registered.
• KernelError::CyclicBundleDependency when the graph has a cycle.

Panics

Panics if a sorted index does not map to a registered bundle (internal invariant).

Trait Implementations

impl Default for BundleRegistry

fn default() -> BundleRegistry

Returns the “default value” for a type.
