Enum ToolExecutionStrategy 

pub enum ToolExecutionStrategy {
    Sequential,
    Parallel {
        max_concurrency: usize,
    },
    Auto,
}

How tool calls should be executed.

Variants

Sequential

Execute tool calls one at a time, in order.

Parallel

Execute tool calls concurrently, up to the given limit.

Fields

max_concurrency: usize

Maximum number of concurrent tool executions.

Auto

Automatically decide based on tool metadata:

• Read-only + concurrency-safe tools → parallel
• Write/destructive tools → sequential
• Requires-approval tools → held until approved
