No-std compatible memoizing selectors for Rust.
Memselect allows you to create efficient selectors for memoizing expensive
computations. The selectors can be composed to create higher-level selectors
that benefit from memoization all the way down. Monomorphization ensures
efficient runtime behavior.
## Example
```rust
use memselect::{new1, new2, Selector2};
let mut computations = 0;
{
let base = new1(|num: u32| num, |num| num * 2);
let mut selector = new2(
base, // You can nest selectors
|num: u32| num * 3,
|num1, num2| { // This function gets the output of `base` and the fn above
computations += 1;
(*num1, *num2)
},
);
assert_eq!(selector.select(2, 3), (4, 9));
assert_eq!(selector.select(2, 3), (4, 9));
}
// Value was computed only once
assert_eq!(computations, 1);
```
