Module types 

Types mirroring the Amazon Bedrock Converse SDK surface.

Structs

CachePointBlock

A prompt-cache breakpoint (Bedrock parity). Placed in message or system content after the prefix to cache: the content part immediately preceding it gets an ephemeral cache_control marker on the wire; the block itself is never emitted. A cache point with no preceding content part in the same message is silently ignored.

ContentBlockDeltaEvent

ContentBlockStartEvent

ContentBlockStartToolUse

ContentBlockStopEvent

ConverseOutput

The top-level response from a converse() call.

GenerateImageOutput

The response of POST /v1/images/generations (spec §8) — the output of the generate_image helper.

GeneratedImage

One generated image: exactly one of url or b64_json is populated.

ImageBlock

An image block (user side).

ImageGenerationUsage

Token consumption for an image generation (absent for providers that do not report it).

InferenceConfiguration

InferenceConfigurationBuilder

Message

A conversation message with a role and one or more content blocks.

The kind of prompt-cache breakpoint.
