16,528View on GitHubClap is a command-line argument parser for Rust that enables developers to define complex interfaces through strongly-typed data structures. It functions as a comprehensive framework for building terminal applications, automating the transformation of raw string inputs into validated, type-safe code representations while simultaneously generating help documentation and usage statements. The library distinguishes itself by offering both a declarative, attribute-based approach and a fluent builder-pattern API, allowing for flexible interface construction. It includes a sophisticated validation
Clap is the most comprehensive Rust argument-parsing library, offering a derive macro for struct-based parsing, subcommand support, automatic help generation, value validation, shell completion generation, and extensive customization — exactly what you need for a CLI application.

Structopt is a Rust library that lets you define CLI arguments as a struct with a derive macro, providing automatic help generation, subcommand support, and default values, which matches the request for a command-line argument parsing library; however, it may not include built-in shell completion generation or custom error messages as part of its core feature set.

argh is a Rust derive-based argument parsing library that supports struct-based parsing, subcommands, and automatic help generation, which directly fits the search for a Rust CLI argument parser — though its focus on minimal code size means it lacks built-in shell completion generation and has limited error customization compared to more full-featured options.
