Client-to-agent event. Discriminated by type field for wire serialization.

Wire Shapes (CANON §3.4)

{"type": "user.message", "content": [{"type": "text", "text": "Hello"}]}
{"type": "user.interrupt"}

Example

use adk_managed::types::{UserEvent, ContentBlock};

let event = UserEvent::Message {
    content: vec![ContentBlock::Text { text: "Hello".to_string() }],
};
let json = serde_json::to_string(&event).unwrap();
assert!(json.contains(r#""type":"user.message""#));

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.

Message

Send a message turn.

Fields

content: Vec<ContentBlock>

The message content blocks.

Interrupt

Interrupt the current turn.

ToolConfirmation

Approve or deny a tool confirmation request.

Fields

tool_use_id: String

The tool use ID being confirmed.

result: ConfirmationResult

Whether to allow or deny.

deny_message: Option<String>

Optional message explaining why the tool was denied.

CustomToolResult

Return results for a client-executed custom tool.

Fields

custom_tool_use_id: String

The custom tool use ID this result corresponds to.

content: Vec<ContentBlock>

The result content blocks.

ToolResult

Return results for a built-in tool (self-hosted only). In hosted topology, built-in tools execute server-side in the sandbox.

Fields

tool_use_id: String

The tool use ID this result corresponds to.

content: Vec<ContentBlock>

The result content blocks.

DefineOutcome

Define success criteria for the session.

Fields

criteria: String

The success criteria description.
