Struct ReflectService 

pub struct ReflectService { /* private fields */ }

Reflection and service-resolution API bound to a context.

Implementations

impl ReflectService

pub fn get<T>(&self, name: &str, strict: bool) -> Result<Option<Arc<T>>>

where T: Send + Sync + 'static,

Read and downcast a service.

pub fn get_value(&self, name: &str, strict: bool) -> Result<Option<Value>>

Read a type-erased service or accessor result.

pub fn require<T>(&self, name: &str) -> Result<Arc<T>>

where T: Send + Sync + 'static,

Require and downcast an active service.

pub fn provide_value( &self, name: String, value: Value, check: Option<Arc<dyn Fn(&Value) -> bool + Send + Sync + 'static>>, ) -> Result<EffectHandle>

Register a type-erased service and optional availability predicate.

pub fn provide_checked<T, F>( &self, name: impl Into<String>, value: T, check: F, ) -> Result<EffectHandle>

where T: Send + Sync + 'static, F: Fn(&T) -> bool + Send + Sync + 'static,

Register a service with an availability predicate.

pub fn set_value(&self, name: &str, value: Value) -> Result<()>

Replace a service or computed property value.

pub fn accessor(&self, name: String, accessor: Accessor) -> Result<EffectHandle>

Define a dynamic computed context property.

pub fn alias( &self, alias: impl Into<String>, target: impl Into<String>, ) -> Result<EffectHandle>

Alias one reflected service name to another. This is the explicit Rust counterpart of the original dynamic mixin() forwarding.

pub fn notify<I, S>(&self, names: I) -> Vec<Fiber>

where I: IntoIterator<Item = S>, S: AsRef<str>,

Re-evaluate fibers that inject any of the named services.

This is useful after an availability predicate registered with provide_checked changes without replacing the service value. The returned fibers were in a matching isolation scope and were asked to reconcile.

pub fn properties(&self) -> HashMap<String, Property>

List reflected property declarations.

pub fn services(&self) -> Vec<ServiceInfo>

List concrete service implementations in all isolation scopes.
