Crate comptools 

Macros for Python-like list comprehension creation of iterators.

Another Crate that tries to bring the simplicty of Python’s syntax to Rust iterators.

The main macro is iter, and other macros are extensions of the latter.

Examples

Below, small examples of how the macros work:

use comptools::*;

let vec: Vec<u64> = vect![x*x; for x in 0..=10; if x % 2 == 0];
assert_eq!(vec, vec![0, 4, 16, 36, 64, 100]);

let sum: u64 = sum![x*x; for x in 1..; while x*x*x < 1234];
assert_eq!(sum, 385);

Macros

iter

Create an iterator using Python’s list-comprehension style.

product

Return product of values of an iterator using Python’s list-comprehension style.

sum

Return sum of values of an iterator using Python’s list-comprehension style.

vect

Create a collection using Python’s list-comprehension style.
