Struct DefaultResolver 

pub struct DefaultResolver<S, K, V>
where
    S: ResolverState,
    K: Borrow<str> + PartialEq<String> + Eq + Hash,
{ /* private fields */ }

General-purpose resolver that stores values indexed by name.

DefaultResolver uses a HashMap internally. While the resolve() method has O(1) complexity, its performance is slower compared to other specialized resolvers such as SmallResolver or IndexedResolver.

Advantages

• No restrictions on variable or function names.
• Performance remains stable even with a large number of items.
• No size limit.

Disadvantages

• Slow resolving names due to the hashing algorithm.

Examples

use fee::DefaultResolver;
use fee::prelude::*;

let mut var_resolver = DefaultResolver::empty();
var_resolver.insert("p0", 10.0);

assert_eq!(*var_resolver.resolve("p0").unwrap(), 10.0);
