Trait MutFunc 

pub trait MutFunc<T> {
    // Required methods
    fn map<F>(self, f: F) -> Self
       where F: FnMut(&mut T);
    fn mmap<F>(&mut self, f: F)
       where F: FnMut(&mut T);
    fn conc(self, other: Self) -> Self;
}

Required Methods

fn map<F>(self, f: F) -> Self

where F: FnMut(&mut T),

fn mmap<F>(&mut self, f: F)

where F: FnMut(&mut T),

fn conc(self, other: Self) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<T> MutFunc<T> for Vec<T>

fn map<F>(self, f: F) -> Self

where F: FnMut(&mut T),

use fnrs::MutFunc;
assert_eq!(vec![3,6,9],vec![1,2,3].map(|x| *x *= 3));

fn mmap<F>(&mut self, f: F)

where F: FnMut(&mut T),

use fnrs::MutFunc;
let mut x = vec![0,1,2];
x.mmap(|x| *x += 1);
assert_eq!(x, vec![1,2,3]);

fn conc(self, other: Self) -> Self

use fnrs::MutFunc;
let x = vec![0,1,2];
let y = vec![0,1,2];
assert_eq!(x.conc(y), vec![0,1,2,0,1,2]);
