Struct EngineConfig 

pub struct EngineConfig {
    pub stream_queue_capacity: usize,
    pub synthesis_stage_budget: Duration,
    pub synthesis_frame_budget: Duration,
    pub enroll_stage_budget: Duration,
    pub admission: AdmissionPolicy,
}

Fixed limits for one engine instance.

Fields

stream_queue_capacity: usize

Capacity for each independent PCM and event queue.

synthesis_stage_budget: Duration

Wall time allowed for one synthesis stage before the per-frame allowance is added.

This is the startup grace: prefill, cache warmup, and the first frame. It is not the whole stage’s ceiling — see Self::synthesis_frame_budget, which extends the deadline as frames are actually produced. A generator that never yields its first frame still trips at exactly this value, so this remains the knob that catches a hang.

synthesis_frame_budget: Duration

Wall time added to the synthesis deadline for each frame already generated.

This is what makes the budget scale with the length of the utterance instead of refusing long ones. Zero is rejected by Self::validate: it would silently restore the flat whole-stage deadline this field exists to replace.

enroll_stage_budget: Duration

Maximum wall time for one enrollment CPU stage.

admission: AdmissionPolicy

Predicted-peak-memory policy applied to every synthesis request.
