# Interner
Fast general-purpose interners for every use case
Interners take complex values and map them to [trivially-comparable stand-ins](https://en.wikipedia.org/wiki/Flyweight_pattern) that can later be resolved back to their source values.
Interners are often found in software like parsers, language interpreters, and compilers; they can be used whenever a given algorithm compares its inputs by identity only.
## Examples
```swift
import Interner
let interner = Interner()
let string = "Hello"
let symbol = interner.interned(string)
let resolved = interner.lookup(symbol)
XCTAssert(resolved == string)
```
