Examples

• Std

  use std::{net::TcpStream, io::Read};
  use peekable::Peekable;
  
  let conn = TcpStream::connect("127.0.0.1:8080").unwrap();
  let mut peekable = Peekable::from(conn);
  
  let mut peeked = [0; 16];
  peekable.peek_exact(&mut peeked).unwrap();
  
  let mut readed = [0; 16];
  peekable.read_exact(&mut readed).unwrap();
  
  assert_eq!(peeked, readed);
  

• Tokio I/O

  use tokio::{net::TcpStream, io::AsyncReadExt};
  use peekable::tokio::AsyncPeekable;
  
  let conn = TcpStream::connect("127.0.0.1:8080").await.unwrap();
  let mut peekable = AsyncPeekable::from(conn);
  
  let mut peeked = [0; 16];
  peekable.peek_exact(&mut peeked).await.unwrap();
  
  let mut readed = [0; 16];
  peekable.read_exact(&mut readed).await.unwrap();
  
  assert_eq!(peeked, readed);
  

• Futures I/O
