gkquad

Build Status Build status Version docs License: MIT Twitter: Kogia_sima

Numerical Integration Library for Rust

Features

  • Compatible with latest stable/beta/nightly Rust compiler
  • Compatible with no_std
  • Extremely fast and simple API
  • Semi-verified computation (You can specify the maximum calculation tolerance)
  • Lightweight (small dependencies)
  • Highly extensible (you can implement a new algorithm)

Note: no_std compatibility

gkquad depends on alloc crate, so you have to specify the global allocator in order to use gkquad.

If you want to use this crate in no_std environment, you must disable the std feature flag.

[dependencies.gkquad]
version = "0.0.4"
