Struct FunctionResponseData 

pub struct FunctionResponseData {
    pub name: String,
    pub response: Value,
    pub inline_data: Vec<InlineDataPart>,
    pub file_data: Vec<FileDataPart>,
}

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling Data for a function (tool) response, including optional multimodal parts.

Fields

name: String

Name of the function that produced this response.

response: Value

The JSON response payload from the function.

inline_data: Vec<InlineDataPart>

Optional inline binary data parts (images, audio, PDFs). Each part is validated against MAX_INLINE_DATA_SIZE on construction.

file_data: Vec<FileDataPart>

Optional file data references (URIs to external files).

Implementations

impl FunctionResponseData

pub fn new(name: impl Into<String>, response: Value) -> FunctionResponseData

Create with JSON response only (backward-compatible).

Example

use adk_core::FunctionResponseData;

let frd = FunctionResponseData::new("my_tool", serde_json::json!({"status": "ok"}));
assert!(frd.inline_data.is_empty());
assert!(frd.file_data.is_empty());

pub fn with_inline_data( name: impl Into<String>, response: Value, inline_data: Vec<InlineDataPart>, ) -> FunctionResponseData

Create with JSON response and inline data parts.

Panics

Panics if any inline data part exceeds MAX_INLINE_DATA_SIZE (10 MB).

pub fn with_file_data( name: impl Into<String>, response: Value, file_data: Vec<FileDataPart>, ) -> FunctionResponseData

Create with JSON response and file data references.

pub fn with_multimodal( name: impl Into<String>, response: Value, inline_data: Vec<InlineDataPart>, file_data: Vec<FileDataPart>, ) -> FunctionResponseData

Create with JSON response, inline data, and file data.

Panics

Panics if any inline data part exceeds MAX_INLINE_DATA_SIZE (10 MB).

pub fn from_tool_result( name: impl Into<String>, value: Value, ) -> FunctionResponseData

Construct from a tool’s return value, preserving multimodal parts if present.

If value is a JSON object containing inline_data or file_data arrays (matching the FunctionResponseData schema), the multimodal parts are extracted and the response field is used as the JSON payload. Otherwise, the entire value is used as a plain JSON response (backward-compatible).

This allows tools to return multimodal data by including inline_data and/or file_data in their JSON return value.

Trait Implementations

fn clone(&self) -> FunctionResponseData

Returns a duplicate of the value.
