what can I replace SubcommandRequiredElseHelp with?

[igotfr]

the code is:

Command::new("sea-orm-cli")
        .version(env!("CARGO_PKG_VERSION"))
        .subcommand(entity_subcommand)
        .subcommand(migrate_subcommands)
        .arg(
            Arg::new("VERBOSE")
                .long("verbose")
                .short('v')
                .help("Show debug messages")
                .takes_value(false)
                .global(true),
        )
        .setting(AppSettings::SubcommandRequiredElseHelp)

the migration guide and list of breaking changes lists:

• (validation) clap::Command::subcommand_required(true).arg_required_else_help(true) is now preferred over clap::AppSettings::SubcommandRequiredElseHelp (Derive should only show help when argc==1 rather than missing subcommand #3280

I did:

Command::new("sea-orm-cli")
        .version(env!("CARGO_PKG_VERSION"))
        .subcommand(entity_subcommand)
        .subcommand(migrate_subcommands)
        .arg(
            Arg::new("VERBOSE")
                .long("verbose")
                .short('v')
                .help("Show debug messages")
                .takes_value(false)
                .global(true),
        )
        .setting(Command::subcommand_required(true).arg_required_else_help(true));

what is my mistake?

Note that it is describing functions on Command which most likely will operate on an instance You can double check in the docs that these are chained methods, like version, giving you:

Command::new("sea-orm-cli")
        .version(env!("CARGO_PKG_VERSION"))
        .subcommand(entity_subcommand)
        .subcommand(migrate_subcommands)
        .arg(
            Arg::new("VERBOSE")
                .long("verbose")
                .short('v')
                .help("Show debug messages")
                .takes_value(false)
                .global(true),
        )
        .subcommand_required(true).arg_required_else_help(true);

Something else that can help is to search the repo for examples
