Struct WorkloadRegistry 

pub struct WorkloadRegistry { /* private fields */ }

Explicit registry of workload backend factories keyed by provider name.

Implementations

impl WorkloadRegistry

pub fn new() -> Self

Create an empty registry. No provider is registered implicitly.

pub fn register( &mut self, name: impl Into<String>, factory: Arc<dyn ManagerFactory>, ) -> AppResult<()>

Register a backend factory under name.

Errors

Returns ErrorCode::InvalidInput for an empty name and ErrorCode::AlreadyExists when the name is already registered.

pub fn contains(&self, name: &str) -> bool

Return true when a provider is registered under name.

The name is trimmed before lookup, matching register and build.

pub fn len(&self) -> usize

Number of registered providers.

pub fn is_empty(&self) -> bool

Return true when no providers are registered.

pub fn names(&self) -> Vec<String>

Registered provider names in deterministic (sorted) order.

pub async fn build( &self, config: &WorkloadConfig, ) -> AppResult<Arc<dyn Manager>>

Build the manager selected by WorkloadConfig::provider.

Errors

Returns ErrorCode::MissingField when the configured provider is empty and ErrorCode::NotFound when it is not registered; otherwise the factory’s own error is propagated.
