description	How to author custom commands for the discriminated-union-with-nested-oneof CLI using the co-generated SDK.

Custom Commands for discriminated-union-with-nested-oneof

Overview

The discriminated-union-with-nested-oneof CLI supports user-authored custom commands that are compiled into the binary alongside the auto-generated API commands. Custom commands get a fully-wired SDK client that inherits the CLI's auth, retries, TLS, base URL, and global headers — zero configuration required.

Architecture

cli/discriminated-union-with-nested-oneof/custom.rs    ← Your command handlers (protected by .fernignore)
cli/discriminated-union-with-nested-oneof/sdk.rs       ← Generated bridge: client() + block_on()
cli/discriminated-union-with-nested-oneof/main.rs      ← Generated entrypoint (calls custom::register)
discriminated-union-with-nested-oneof-sdk/             ← Co-generated typed SDK crate
discriminated-union-with-nested-oneof-types/           ← Co-generated typed model crate

Adding a Custom Command

1. Edit cli/discriminated-union-with-nested-oneof/custom.rs

This file is protected by .fernignore — fern generate will never overwrite it. Register commands in the register() function:

use discriminated_union_with_nested_oneof_sdk::api::*;

pub fn register(app: CliApp) -> CliApp {
    let app = app.command(
        clap::Command::new()
            .()
            .(clap::Arg::().()),
        |matches, ctx| {
              = matches.get_one::<>().();
              = super::sdk::(ctx);
              = super::sdk::(
                client.resource.(id),
            )?;
            (, serde_json::(&result).());
            (())
        },
    );
    app
}
