Struct StreamSubstitution 

pub struct StreamSubstitution {
    pub model_id: String,
    pub substituted_from: Option<String>,
    pub substitution_reason: Option<FallbackReason>,
}

What StreamEvent::Substituted reports.

Fields

model_id: String

The installed on-device model that is serving the stream.

substituted_from: Option<String>

The model the request was routed to — the first candidate the chain moved past. None only if no hop was recorded.

substitution_reason: Option<FallbackReason>

Why Self::substituted_from did not serve.

Implementations

impl StreamSubstitution

pub fn annotate(&self, frame: &mut Value)

Put the substitution on a consumer’s terminal frame as local_last_resort: true plus substituted_from / substitution_reason — the field names the non-streaming surfaces already use, so one vocabulary covers every path.

Trait Implementations
