vec_remove_if
Extract elements from a vector based on supplied criteria
Project by SnS Development
Problem
Need to filter some elements out of an existing Vector through a mutable borrow
Solution
A trait implemented on Vec<T>
with 2 functions remove_if
and
swap_remove_if
that iterate over elements, runs a supplied closure,
and removes elements where the closure returns [true].
Example
use vec_remove_if::VecRemoveIf;
let mut v = vec![1, 12, 3, 14, 5, 16, 7, 18];
assert_eq!(
vec![12, 14, 16, 18],
v.remove_if(|e| e > &10)
);
assert_eq!(
vec![1, 3, 5, 7],
v
);
