Struct EmitterConfig 

pub struct EmitterConfig {
    pub buffer_size: usize,
    pub drop_policy: DropPolicy,
    pub coalesce_interval_ms: u64,
    pub include_trace_id: bool,
    pub include_trace_ctx: bool,
}

Configuration for event emission backpressure and coalescing.

When the frontend cannot consume events as fast as they are produced (e.g., rapid-fire progress updates), this config controls buffering and deduplication behavior.

Fields

buffer_size: usize

Maximum number of pending events before the drop policy kicks in. Default: 256.

drop_policy: DropPolicy

What to do when the buffer is full. Default: DropNewest.

coalesce_interval_ms: u64

Minimum interval between events of the same type for the same job. Events arriving faster than this interval are coalesced (only the latest value is kept). Default: 50 ms.

include_trace_id: bool

👎Deprecated since 0.3.0:

Use include_trace_ctx instead

Whether to include a trace_id field on emitted events (if available). Default: false (legacy — use include_trace_ctx instead).

Phase status: compatibility / migration-only. The trace_id is a plain string extracted from job_queue::QueueJob. The canonical replacement is include_trace_ctx. When include_trace_ctx is true, trace strings are preserved regardless of this flag.

Removal condition: removed when all UI consumers migrate to TraceCtx.

include_trace_ctx: bool

Whether to propagate canonical trace context on emitted events. Default: true.

When true, the legacy trace_id: Option<String> field is preserved on events so that downstream consumers can convert it to a TraceCtx via trace_ctx_from_event_trace_id.

This flag is the canonical replacement for include_trace_id. When both flags disagree, include_trace_ctx takes precedence: if include_trace_ctx is true the trace string is kept even when include_trace_id is false.

Phase status: current / canonical.
