Module executor 

Process execution abstraction for dependency injection.

This module provides a trait-based abstraction for executing external processes, allowing production code to use real processes and test code to use mocks. This follows the same pattern as AppEffectHandler for dependency injection.

Purpose

• Production: RealProcessExecutor executes actual commands using std::process::Command
• Tests: MockProcessExecutor captures calls and returns controlled results

Benefits

• Test isolation: Tests don’t spawn real processes
• Determinism: Tests produce consistent results
• Speed: Tests run faster without subprocess overhead
• Mockability: Full control over process behavior in tests

Structs

AgentChildHandle

Result of spawning an agent process.

AgentCommandResult

Result of an agent command execution (for testing).

AgentSpawnConfig

Configuration for spawning an agent process with streaming support.

ProcessOutput

Output from an executed process.

RealAgentChild

Wrapper for real std::process::Child.

RealProcessExecutor

Real process executor that uses std::process::Command.

Traits

AgentChild

Trait for interacting with a spawned agent child process.

ProcessExecutor

Trait for executing external processes.
