Enum ToolExecutionStrategy 

pub enum ToolExecutionStrategy {
    Sequential,
    Parallel,
    Auto,
}

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling Controls how multiple tool calls from a single LLM response are dispatched.

Variants

Sequential

Execute tools one at a time in LLM-returned order. Default.

Parallel

Execute all tools concurrently without inspecting tool metadata.

This is an explicit caller override. The caller is responsible for ensuring every selected tool is safe to execute concurrently.

Auto

Execute calls whose tools report both read-only and concurrency-safe concurrently, then execute all remaining calls sequentially.
