//! Boolean metadata parsing helpers.
//!
//! These helpers normalize queue flags from either JSON booleans or common
//! string spellings such as `yes` and `off`.
//!
//! # Examples
//!
//! ```ignore
//! let execute = metadata_bool(&metadata, &["execute"]);
//! ```

use super::metadata_lookup::metadata_lookup;

/// Parses a boolean value from queue metadata.
///
/// String forms such as `true`, `false`, `yes`, and `off` are accepted in
/// addition to native JSON booleans.
///
/// # Examples
///
/// ```ignore
/// let execute = metadata_bool(&metadata, &["execute"]).unwrap_or(false);
/// ```
