Enum AgentEvent 

#[non_exhaustive]
pub enum AgentEvent {
    TextDelta(String),
    TurnCompleted,
    ToolCallStarted {
        id: String,
        name: String,
        arguments: String,
    },
    ToolCallCompleted {

        output: String,
        is_error: bool,
    },
}

Streaming events emitted by an crate::Agent as a turn unfolds.

Attach an EventSink to a crate::Config to observe these live — for example to render tokens to a terminal as they arrive, or to surface tool activity in a UI.

#[non_exhaustive] because new event kinds will be added over time; match with a _ arm so a new variant is not a breaking change.

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.

TextDelta(String)

A chunk of assistant text was produced.

TurnCompleted

The assistant finished a text/tool turn (one round-trip to the model).

ToolCallStarted

The model requested a tool call (fired before the tool runs).

Fields

id: String

Provider-assigned call id.

name: String

Tool name.

arguments: String

Raw JSON argument string as sent by the model.

ToolCallCompleted

A tool finished running.

Fields

id: String

Provider-assigned call id.

name: String

Tool name.

output: String

The tool’s textual output (truncated for display upstream if needed).

is_error: bool

Whether the tool reported an error.
