Re-exported normalized LLM request data types.

## Structs

* [AnnotatedLlmRequest](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-annotatedllmrequest): Structured view of an LLM request, produced by a Codec from opaque [`LlmRequest`](/reference/api/rust-library-reference/nemo-relay/api/llm/struct-llmrequest) content.
* [FunctionCall](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-functioncall): A function call within a tool call.
* [FunctionDefinition](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-functiondefinition): A function definition within a tool definition.
* [GenerationParams](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-generationparams): Normalized generation parameters across providers.
* [OpenAiImageUrl](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-openaiimageurl): OpenAI image URL payload.
* [ToolCall](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-toolcall): A tool call requested by the assistant.
* [ToolChoiceFunction](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-toolchoicefunction): A specific tool choice that forces a named function.
* [ToolChoiceFunctionName](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-toolchoicefunctionname): The name component of a specific tool choice.
* [ToolDefinition](/reference/api/rust-library-reference/nemo-relay/codec/request/struct-tooldefinition): A tool definition (function schema) available to the model.

## Enums

* [ContentPart](/reference/api/rust-library-reference/nemo-relay/codec/request/enum-contentpart): A single content part within a multimodal message.
* [Message](/reference/api/rust-library-reference/nemo-relay/codec/request/enum-message): A single message in a conversation, tagged by role.
* [MessageContent](/reference/api/rust-library-reference/nemo-relay/codec/request/enum-messagecontent): Message content: either a plain string or multimodal parts array.
* [ToolChoice](/reference/api/rust-library-reference/nemo-relay/codec/request/enum-toolchoice): Tool choice control: how the model should use available tools.
