Struct ToolResultBlock 

pub struct ToolResultBlock { /* private fields */ }

Tool execution result sent back to the model.

After executing a tool requested via ToolUseBlock, the application creates a ToolResultBlock containing the tool’s output and sends it back to the model. The model then uses this information in its next response.

Fields

• tool_use_id: Must match the id from the corresponding ToolUseBlock
• content: JSON result from the tool execution

Example

use open_agent::{ToolResultBlock, ContentBlock};
use serde_json::json;

let result = ToolResultBlock::new(
    "call_123",
    json!({"result": 4})
);
assert_eq!(result.tool_use_id(), "call_123");

Implementations

impl ToolResultBlock

pub fn new(tool_use_id: impl Into<String>, content: Value) -> Self

Creates a new tool result block.

Parameters

• tool_use_id: ID from the corresponding ToolUseBlock
• content: JSON result from tool execution

Example

use open_agent::ToolResultBlock;
use serde_json::json;

let result = ToolResultBlock::new(
    "call_xyz",
    json!({
        "status": "success",
        "data": {"temperature": 72}
    })
);

pub fn tool_use_id(&self) -> &str

Returns the ID of the tool use request this result corresponds to.

Returns the JSON result from executing the tool.
