//! Macros for generating quote summary accessor methods.

/// Generate quote summary accessor methods for Ticker.
///
/// This macro eliminates code duplication by generating accessor methods
/// from a single declaration.
///
/// # Usage
///
/// ```ignore
/// define_quote_accessors! {
///     /// Get price information
///     price -> Price, price,
///
///     /// Get summary detail
///     summary_detail -> SummaryDetail, summary_detail,
/// }
/// ```
///
/// This generates:
/// - `Ticker::price(&self) -> Result<Option<Price>>`
///
/// Each method:
/// 1. Ensures quote summary data is loaded
/// 2. Reads from cache
/// 3. Clones and returns the typed module data
