Struct std::stream::FromIter

source · [−]

pub struct FromIter<I> { /* private fields */ }

🔬 This is a nightly-only experimental API. (stream_from_iter #81798)

Expand description

A stream that was created from iterator.

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