Struct futures_util::stream::RepeatWith

source · [−]

pub struct RepeatWith<F> { /* private fields */ }

Expand description

An stream that repeats elements of type A endlessly by applying the provided closure F: FnMut() -> A.

This struct is created by the repeat_with() function. See its documentation for more.
