Struct ReactionRuntimeContext 

pub struct ReactionRuntimeContext {
    pub instance_id: String,
    pub reaction_id: String,
    pub status_tx: ComponentEventSender,
    pub state_store: Option<Arc<dyn StateStoreProvider>>,
    pub identity_provider: Option<Arc<dyn IdentityProvider>>,
}

Context provided to Reaction plugins during initialization.

Contains Arc<T> instances for all drasi-lib provided services. DrasiLib constructs this context when a reaction is added via add_reaction().

Available Services

• instance_id: The DrasiLib instance ID (for log routing isolation)
• reaction_id: The unique identifier for this reaction instance
• status_tx: Channel for reporting component status/lifecycle events
• state_store: Optional persistent state storage (if configured)

Clone

This struct implements Clone and all fields use Arc internally, making cloning cheap (just reference count increments).

Fields

instance_id: String

DrasiLib instance ID (for log routing isolation)

reaction_id: String

Unique identifier for this reaction instance

status_tx: ComponentEventSender

Channel for reporting component status/lifecycle events.

Use this to send status updates (Starting, Running, Stopped, Error) back to DrasiLib for monitoring and lifecycle management.

state_store: Option<Arc<dyn StateStoreProvider>>

Optional persistent state storage.

This is Some if a state store provider was configured on DrasiLib, otherwise None. Reactions can use this to persist state across restarts.

identity_provider: Option<Arc<dyn IdentityProvider>>

Optional identity provider for credential injection.

This is Some if the host has configured an identity provider for this component. Reactions can use this to obtain authentication credentials (passwords, tokens, certificates) for connecting to external systems.

Implementations

impl ReactionRuntimeContext

pub fn new( instance_id: impl Into<String>, reaction_id: impl Into<String>, status_tx: ComponentEventSender, state_store: Option<Arc<dyn StateStoreProvider>>, ) -> Self

Create a new reaction runtime context.

This is typically called by ReactionManager when adding a reaction to DrasiLib. Plugin developers do not need to call this directly.

Arguments

• instance_id - The DrasiLib instance ID
• reaction_id - The unique identifier for this reaction
• status_tx - Channel for reporting component status/lifecycle events
• state_store - Optional persistent state storage
• query_provider - Access to query instances for subscription

pub fn instance_id(&self) -> &str

Get the DrasiLib instance ID.

pub fn reaction_id(&self) -> &str

Get the reaction’s unique identifier.

pub fn status_tx(&self) -> &ComponentEventSender

Get a reference to the status channel.

pub fn state_store(&self) -> Option<&Arc<dyn StateStoreProvider>>

Get a reference to the state store if configured.

Trait Implementations

impl Clone for ReactionRuntimeContext

fn clone(&self) -> ReactionRuntimeContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReactionRuntimeContext

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

Formats the value using the given formatter.
