RustyLine is a Rust library implementing GNU Readline-style line editing, based on Antirez's Linenoise. It provides interactive prompt features such as history, word and filename completion, hints, and multi-line editing for building command-line interfaces.

Use cases

• build an interactive REPL prompt in Rust
• add command history and line editing to a CLI tool
• implement tab completion for a shell-like application
• read user input with readline-style keybindings
• create an interactive console for a Rust application
• add persistent command history to a terminal program

When to choose

• you are writing a Rust CLI or REPL that needs polished interactive line input
• you want a lightweight readline alternative without C dependencies
• you need Unicode support, completion, hints, and history search in a terminal prompt

When to avoid

• you need full GNU Readline compatibility or advanced features like bracketed paste macros
• your application runs in unsupported terminals such as Mintty or PowerShell ISE
• you are not building an interactive terminal input loop
