One event from an Anthropic streaming response.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MessageStart

Opens the response. Carries usage and the empty message envelope, neither of which the SDK needs.

ContentBlockStart

Opens a content block at index, declaring what kind it is.

Fields

index: u32

Position of the block within the response.

content_block: AnthropicBlockStart

The block’s kind, and its identity when it is a tool call.

ContentBlockDelta

Appends to the block at index.

Fields

index: u32

Position of the block being appended to.

delta: AnthropicDelta

The fragment to append, tagged by which channel it belongs to.

ContentBlockStop

Closes the block at index.

Fields

index: u32

Position of the block being closed.

MessageDelta

Reports top-level message changes; this is where stop_reason arrives.

Fields

delta: AnthropicMessageDelta

The changed fields.

MessageStop

Ends the response.

Ping

Keep-alive. Carries nothing.

Error

A mid-stream error, such as an overload. Terminates the response.

Fields

error: AnthropicErrorBody

The error body.

Unknown

An event type this SDK does not recognise, ignored rather than fatal.
