Struct EventContext 

#[non_exhaustive]
pub struct EventContext {
    pub message: InboundMessage,
    pub container: Arc<FrozenDiContainer>,
    pub trace: TraceContext,
    pub tenant: Option<Arc<TenantConfig>>,
}

What an #[EventPattern] handler receives — DI + payload + trace, no HTTP types anywhere.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message: InboundMessage

container: Arc<FrozenDiContainer>

trace: TraceContext

Continues the producer’s trace (or a fresh root when none was carried).

tenant: Option<Arc<TenantConfig>>

The envelope’s tenant, resolved + validated against the same TenantRegistry as HTTP traffic (suspended tenants never reach handlers — their events are dead-lettered upstream).

Implementations

impl EventContext

pub fn inject<T: Send + Sync + 'static>(&self) -> &T

Resolve a singleton service. O(1), no locks. Panics when absent.

pub fn try_inject<T: Send + Sync + 'static>(&self) -> Option<&T>

Non-panicking variant of Self::inject.

pub fn payload<T: DeserializeOwned>(&self) -> Result<T, EventError>

Deserialize the payload into a typed event.

A malformed payload is permanent by definition, so the error is already EventError::DeadLetter — ctx.payload()? does the right thing without manual mapping.

pub fn traceparent(&self) -> String

traceparent for forwarding to the next hop (HTTP call, next queue).
