Struct AgentOutput 

#[non_exhaustive]
pub struct AgentOutput {
    pub value: Value,
    pub session_id: Option<String>,
    pub cost_usd: Option<f64>,
    pub input_tokens: Option<u64>,
    pub output_tokens: Option<u64>,
    pub model: Option<String>,
    pub duration_ms: u64,
    pub debug_messages: Option<Vec<DebugMessage>>,
}

Raw output returned by an AgentProvider after a successful invocation.

Carries the agent’s response value together with usage and billing metadata.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

value: Value

The agent’s response. A plain Value::String for text mode, or an arbitrary JSON value when a JSON schema was requested.

session_id: Option<String>

Provider-assigned session identifier, useful for resuming conversations.

cost_usd: Option<f64>

Total cost in USD for this invocation, if reported by the provider.

input_tokens: Option<u64>

Number of input tokens consumed, if reported.

output_tokens: Option<u64>

Number of output tokens generated, if reported.

model: Option<String>

The concrete model identifier used (e.g. "claude-sonnet-4-20250514").

duration_ms: u64

Wall-clock duration of the invocation in milliseconds.

debug_messages: Option<Vec<DebugMessage>>

Conversation trace captured when AgentConfig::verbose is true.

Contains every assistant message and tool call made during the invocation, in chronological order. None when verbose mode is off.
