Struct SubagentResult 

pub struct SubagentResult {
    pub name: String,
    pub final_response: String,
    pub total_turns: usize,
    pub tool_count: u32,
    pub tool_logs: Vec<ToolCallLog>,
    pub usage: TokenUsage,
    pub success: bool,
    pub duration_ms: u64,
    pub error_details: Option<String>,
    pub failed_tool: Option<String>,
}

Result from a subagent execution.

Fields

name: String

Name of the subagent.

final_response: String

The final text response (only visible part to parent).

total_turns: usize

Total number of turns taken.

tool_count: u32

Number of tool calls made by the subagent.

tool_logs: Vec<ToolCallLog>

Log of tool calls made by the subagent.

usage: TokenUsage

Token usage statistics.

success: bool

Whether the subagent completed successfully.

duration_ms: u64

Duration in milliseconds.

error_details: Option<String>

Detailed error information when success is false.

Contains the raw error message from the agent event, which may include stack trace information or structured error context.

failed_tool: Option<String>

Retained for serialization compatibility with older clients.

The previous implementation inferred this from the “last pending tool” when any generic error occurred, which was incorrect for LLM or transport failures. The field is currently never populated until the SDK has deterministic error provenance.
