Benchmarks comparing `feature/input_trait` with `experiment/impl_trait`
View chomp_impl_trait_performance_results.md

experiment/impl_trait is essentially a reimplementation of all the parsers and combinators using the same baseline code as feature/input_trait. The feature/input_trait is intended to be chomp 0.3, and experiment/impl_trait either 1.0 or maybe a new crate chomp2 (useful since feature/input_trait still works on stable while experiment/impl_trait requires the latest nightly version of rustc).

Both share the same reposiotory and dependencies, just two different branches. Same code is used for both tests, with slight adjustment for how parsers are structured.

WIP of pre-RFC for saturating and wrapping integer wrapper types

  • Feature Name: saturating-and-checking-integer-wrapper-types
  • Start Date: (fill me in with today's date, YYYY-MM-DD)
  • RFC PR: (leave this empty)
  • Rust Issue: (leave this empty)

Summary

Implement two wrapper-types in std::num which provide two different types of behavior on overflow: saturating arithmetic and always checked arithmetic with the latter signalling a thread panic on

extern crate rsz;
use rsz::{FunctorMut, HKT, MonadMut, Unit};
// Let's say that this type requires to run the closure multiple times,
// so we can only implement the mutable monads.

inner: T,
