[−][src]Crate tee_readwrite
tee_readwrite
This module allows you to mirror read/writes to another read/write (like POSIX tee)
Examples
TeeReader
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![]; assert_eq!(tee.read_to_end(&mut results).expect("read"), 3); // consume the tee, returning the reader and the mirroring writer let (_read, output) = tee.into_inner(); assert_eq!(results, output);
TeeWriter
use tee_readwrite::{TeeReader, TeeWriter}; let writer = vec![]; let mut tee = TeeWriter::new(writer, vec![]); for i in 1..=3 { let _ = tee.write_all(&[i]); } // we can borrow the output writer assert_eq!(tee.borrow_output(), &[1,2,3]); // consume the tee, returning the writer and its tee output let (left, output) = tee.into_inner(); assert_eq!(left, output); assert_eq!(output, &[1,2,3]);
Structs
TeeReader | Mirror all reads from an std::io::Read and writes them to a std::io::Write |
TeeWriter | Mirror all writes to a std::io::Write to another std::io::Write |
