//! # Switchboard On-Demand Oracle SDK
//!
//! Official Rust SDK for Switchboard On-Demand Oracles on Solana.
//!
//! This SDK provides secure, efficient access to real-time oracle data with
//! comprehensive validation and zero-copy performance optimizations.
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use switchboard_on_demand::prelude::*;
//!
//! // Configure the verifier with required accounts
//! let mut verifier = QuoteVerifier::new();
//! verifier
//!     .queue(&queue_account)
//!     .slothash_sysvar(&slothash_sysvar)
//!     .ix_sysvar(&instructions_sysvar)
//!     .clock(&clock_sysvar)
//!     .max_age(150);
//!
//! // Load and verify the oracle quote
//! let quote = verifier.load_and_verify(0)?;
//!
//! // Access feed data
//! for feed in quote.feeds() {
//!     println!("Feed {}: {}", feed.hex_id(), feed.value());
//! }
//! ```
//!
//! ## Security Considerations
//!
//! - Always validate oracle data freshness with appropriate `max_age` values
//! - Use minimum sample counts for critical operations
//! - Verify feed signatures in production environments
//! - Monitor for stale data and implement appropriate fallback mechanisms
//!
//! ## Feature Flags
//!
//! - `client` - Enable RPC client functionality
//! - `anchor` - Enable Anchor framework integration
