Trait rg3d_core::VecExtensions

pub trait VecExtensions<T> {
    fn retain_mut_ext<F>(&mut self, f: F)
    where
        F: FnMut(&mut T) -> bool;
}

Required methods

fn retain_mut_ext<F>(&mut self, f: F) where
    F: FnMut(&mut T) -> bool, 

Retains only the elements specified by the predicate.

In other words, remove all elements e such that f(&mut e) returns false. This method operates in place, visiting each element exactly once in the original order, and preserves the order of the retained elements.

Notes

This method is the copy of retain method of Vec, but with ability to modify each element.
