This module allows you to mirror read/writes to another read/write (like POSIX tee)
```rust use tee_readwrite::{TeeReader, TeeWriter}; // make a new reader let reader = std::io::Cursor::new(vec![1,2,3]); let mut tee = TeeReader::new( reader, vec![], // vec implements write false // we don't care about flushing here );
// read all of the elements from the cursor into this vec // each 'read' call will be written to the wrapped writer let mut results = vec![]; asserteq!(tee.readto_end(&mut results).expect("read"), 3);
// consume the tee, returning the reader and the mirroring writer let (read, output) = tee.intoinner(); assert_eq!(results, output); ```
```rust use teereadwrite::{TeeReader, TeeWriter}; let writer = vec![]; let mut tee = TeeWriter::new(writer, vec![]); for i in 1..=3 { let _ = tee.writeall(&[i]); } // we can borrow the output writer asserteq!(tee.borrowoutput(), &[1,2,3]);
// consume the tee, returning the writer and its tee output let (left, output) = tee.intoinner(); asserteq!(left, output); assert_eq!(output, &[1,2,3]); ```
