Mutable last element of this container.

pub fn init<'a>(&'a self) -> &'a [T]

View all but last elements of this container.

pub fn push(&mut self, value: T)

Push an element to the end.

pub fn pop(&mut self) -> Option<T>

pub fn insert(&mut self, index: usize, value: T)

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

Retains only the elements specified by the predicate.

In other words, remove all elements e such that f(&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.

Examples

let mut vec = RepeatedField::from(vec![1, 2, 3, 4]);
vec.retain(|&x| x % 2 == 0);
assert_eq!(vec, RepeatedField::from(vec![2, 4]));
