Struct futures::io::CopyInto

pub struct CopyInto<'a, R, W> where
    R: 'a + ?Sized,
    W: 'a + ?Sized,  { /* fields omitted */ }

A future which will copy all data from a reader into a writer.

Created by the copy_into function, this future will resolve to the number of bytes copied or an error if one happens.
