Rust wraper for the 51 Degrees device detection

This wrapper allows the creation and usage of the 51 Degrees device detection hash engine. For more information about 51 Degrees see: https://51degrees.com/documentation/4.4/index.html

Getting started:

 // Lite hash for demo purposes
 let file: PathBuf = "51Degrees-LiteV4.1.hash".into();
 let manager = HashEngineBuilder::new(&file)
     .hash_config(HashConfig::HighPerformance)
     .init()
     .unwrap();
 let ua = "Mozilla/5.0 (iPhone; CPU iPhone OS 16_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.2 Mobile/15E148 Safari/604.1";

 let evidence = Evidence::new_with_user_agent(ua);
 let mut results = manager.process(&evidence).unwrap();
 let res = results.get_str("PlatformName");
 assert_eq!(res, Some("iOS"));

Configuration

Currently switching between hash configs and defining a list of result properties is implemented. Peformance can be switched between:

• HighPerformance
• InMemory
• Balanced
• LowMemory

With the first config being the fastest at the expense of memory footprint and the last one being the opposite.

Properties are a list of static strings that define the values that are put into the result during the processing of the evidence. Limiting the device properties in the result can help speed up the processing of the evidence.
