Struct CopyingSource

Source 
pub struct CopyingSource<S: Source, U: Sink> { /* private fields */ }
Expand description

A source that also copies each read element to the sink

Warning: if a call to write fails, this source will return an error and the element that has been read from the underlying source will be lost
