Struct vec_vec::LendingIter

pub struct LendingIter<'a, T> { /* private fields */ }

A lending iterator over the entries of a Vec<Vec<T>>. In this case, entry implies that it can be dereferenced either as a shared or a mutable reference.

Implementations

impl<'a, T> LendingIter<'a, T>

pub fn container(&self) -> &Vec<Vec<T>>

Returns a shared reference to the Vec<Vec<T>>.
