Struct TraceContext 

pub struct TraceContext {
    pub trace_id: String,
    pub span_id: String,
    pub parent_span_id: Option<String>,
    pub originating_core_id: CoreId,
    pub current_core_id: CoreId,
    pub tenant_id: TenantId,
    pub command_id: Option<String>,
}

Correlation context propagated across distributed Runtime boundaries.

Fields

trace_id: String

End-to-end trace identity.

span_id: String

Current span identity.

parent_span_id: Option<String>

Parent span identity, when this is a child span.

originating_core_id: CoreId

Core that originated the trace.

current_core_id: CoreId

Core currently handling the operation.

tenant_id: TenantId

Tenant isolation boundary.

command_id: Option<String>

Optional command identity associated with the trace.

Implementations

impl TraceContext

pub fn new( trace_id: impl Into<String>, span_id: impl Into<String>, originating_core_id: CoreId, current_core_id: CoreId, tenant_id: TenantId, ) -> Result<TraceContext, RuntimeError>

Creates and validates a root trace context.

pub fn with_command_id( self, command_id: impl Into<String>, ) -> Result<TraceContext, RuntimeError>

Associates a validated command identity with this context.

pub fn child_span( &self, span_id: impl Into<String>, current_core_id: CoreId, ) -> Result<TraceContext, RuntimeError>

Creates a child span for another Core while preserving correlation.
