Struct std::async_iter::FromIter

source ·
pub struct FromIter<I> { /* private fields */ }
🔬This is a nightly-only experimental API. (async_iter_from_iter #81798)
Expand description

An async iterator that was created from iterator.

This async iterator is created by the from_iter function. See it documentation for more.
