Implementations on Foreign Types
fmap for Vec
Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;
fn main() {
let a = c!(1,2,3,4,5);
assert_eq!(a.fmap(|x| x*2f64), seq!(2,10,2));
}
reduce for Vec
Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;
fn main() {
let a = seq!(1,100,1);
assert_eq!(a.reduce(0, |x,y| x + y), 5050f64);
}
Filter for Vec
Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;
fn main() {
let a = c!(1,2,3,4,5);
let b = a.filter(|x| x > 3.);
assert_eq!(b, c!(4,5));
}
Take for Vec
Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;
fn main() {
let a = c!(1,2,3,4,5);
let b = a.take(3);
assert_eq!(b, c!(1,2,3));
}
Skip for Vec
Examples
#[macro_use]
extern crate peroxide;
use peroxide::fuga::*;
fn main() {
let a = c!(1,2,3,4,5);
let b = a.skip(3);
assert_eq!(b, c!(4,5));
}
