let resolver = ResolverChain::new(vec![
  Box::new(NullResolver),
  Box::new(DefaultResolver),
]);

Trait Implementations

impl AssetResolver for ResolverChain

fn resolve(&self, path: &str) -> Option<PathBuf>

Attempt to resolve a path using the resolvers in the chain.

Example

let resolver = ResolverChain::new(vec![
  Box::new(NullResolver),
  Box::new(DefaultResolver),
]);
 
let path = resolver.resolve("/home/user/assets/test.png").unwrap();
assert_eq!(path.to_str().unwrap(), "/home/user/assets/test.png");
