//! JSON renderer for BSS boot parameter output. There is no table
//! variant yet (the BSS payload is too nested for a useful table);
//! callers always get pretty-printed JSON.

use anyhow::Error;

use crate::openapi_client::types::BootParameters;

/// Pretty-print boot parameters as JSON.
pub fn print(boot_parameters: &[BootParameters]) -> Result<(), Error> {
  println!("{}", serde_json::to_string_pretty(boot_parameters)?);
  Ok(())
}

#[cfg(test)]
mod tests {
  //! Pins the JSON-only contract: empty input still produces valid
  //! JSON (`[]`), and the renderer never panics. Catches the kind of
  //! signature regression we hit before (the `output_opt` parameter
  //! used to be threaded in but ignored — it has since been dropped).
