//! # Example

//! 

//! ```

//! use rscache::OsrsCache;

//! use rscache::ldr::osrs::ItemLoader;

//! 

//! # fn main() -> rscache::Result<()> {

//! let cache = OsrsCache::new("./data/cache")?;

//! let item_ldr = ItemLoader::new(&cache)?;

//! 

//! if let Some(def) = item_ldr.load(1042) {

//!     assert_eq!("Blue partyhat", def.name);

//!     assert!(!def.stackable);

//!     assert!(!def.members_only);

//! }

//! # Ok(())

//! # }

//! ```

//! 

//! # Errors

//! 

//! Every loader returns a `CacheError` with an inner error.
