1.0.0[][src]Struct std::iter::FlatMap

#[must_use = "iterators are lazy and do nothing unless consumed"]
pub struct FlatMap<I, U, F> where
    U: IntoIterator
{ /* fields omitted */ }

An iterator that maps each element to an iterator, and yields the elements of the produced iterators.

This struct is created by the flat_map method on Iterator. See its documentation for more.
