The wrapper struct to enable byte counting for std::io::Read,
std::io::Write, std::io::Seek and its asynchronous variants from futures
and tokio crates.
std to enable std::io::{Read, Write, Seek}. Enabled by default.futures to enable futures_io::{AsyncRead, AsyncWrite, AsyncSeek}.tokio to enable tokio::io::{AsyncRead, AsyncWrite, AsyncSeek}.std::io::Read:```rust use std::io::{BufRead, BufReader}; use countio::Counter;
fn main() { let reader = "Hello World!".as_bytes(); let reader = BufReader::new(reader); let mut reader = Counter::new(reader);
let mut buf = String::new();
let len = reader.read_line(&mut buf).unwrap();
assert_eq!(len, reader.reader_bytes());
} ```
std::io::Write:```rust use std::io::{BufWriter, Write}; use countio::Counter;
fn main() { let writer = Vec::new(); let writer = BufWriter::new(writer); let mut writer = Counter::new(writer);
let buf = "Hello World!".as_bytes();
let len = writer.write(buf).unwrap();
writer.flush().unwrap();
assert_eq!(len, writer.writer_bytes());
} ```
