Variants

MessageStart

Fields

message: Option<MessageStart>

Anthropic-compatible relays (Bedrock’s Messages passthrough) can emit message_start with a null message; None is a no-op rather than a corrupt frame.

ContentBlockStart

Fields

index: usize

content_block: Content

ContentBlockDelta

Fields

index: usize

delta: ContentDelta

ContentBlockStop

Fields

index: usize

MessageDelta

Fields

delta: MessageDelta

usage: PartialUsage

MessageStop

Ping

Keep-alive; a Known no-op, not an unknown event to warn about.

Error

Anthropic’s top-level error envelope ({"type":"error","error":{...}}, e.g. overloaded_error). A modeled event, not an unknown to warn-skip: it surfaces as a provider error like every other family’s error envelope. The payload stays a raw Value so every provider field (type, message, extras) survives into the error body.

Fields

error: Value
