Crate vld_clap 

vld-clap — Clap integration for vld

Validate CLI arguments after clap has parsed them, using #[derive(Validate)] directly on the clap struct. No separate schema needed.

Quick Start

use clap::Parser;
use vld::Validate;
use vld_clap::prelude::*;

#[derive(Parser, Debug, serde::Serialize, Validate)]
struct Cli {
    /// Admin email address
    #[arg(long)]
    #[vld(vld::string().email())]
    email: String,

    /// Server port
    #[arg(long, default_value_t = 8080)]
    #[vld(vld::number().int().min(1).max(65535))]
    port: i64,

    /// Application name
    #[arg(long)]
    #[vld(vld::string().min(2).max(50))]
    name: String,
}

fn main() {
    let cli = Cli::parse(); // clap's parse — no conflict
    validate_or_exit(&cli);
    println!("Valid! {:?}", cli);
}
