Struct Repeat

pub struct Repeat { /* private fields */ }

Available on crate feature io-util only.

Expand description

An async reader which yields one byte over and over and over and over and over and…

This struct is generally created by calling repeat. Please see the documentation of repeat() for more details.

This is an asynchronous version of std::io::Repeat.
