Duct is a Rust library for running child processes with shell-like pipelines and IO redirection while avoiding common cross-platform pitfalls. It provides a fluent API for building commands, piping them together, and capturing or streaming output with sensible error handling.

Use cases

• run child processes from Rust code
• build shell-like pipelines programmatically
• capture stdout of a command as a string
• pipe one command's output into another
• merge stderr into stdout and read incrementally
• treat non-zero exit codes as errors by default

When to choose

• you need to spawn and compose subprocesses in Rust without shell quoting bugs
• you want portable process pipelines across Linux, macOS, and Windows
• you prefer ergonomic command execution over std::process boilerplate

When to avoid

• you need advanced shell features like globbing or environment variable expansion
• you only need a single simple subprocess and std::process suffices
• you need asynchronous process management with tokio
