optional_take::io

Adapter for [std::io::Take] that accepts Option<u64> for limit.

Examples

```rust use optional_take::io::Takable; use std::io::{self, Read};

fn main() -> io::Result<()> { let read = b"hello, world"; let mut take = read.take_optional(Some(5)); let mut buf = [0; 10];

let len = take.read(&mut buf)?;
assert_eq!(len, 5);
assert_eq!(std::str::from_utf8(&buf[..len]).unwrap(), "hello");

assert_eq!(take.read(&mut buf).unwrap(), 0);

take.set_limit(None);
let len = take.read(&mut buf)?;
assert_eq!(len, 7);
assert_eq!(std::str::from_utf8(&buf[..len]).unwrap(), ", world");

Ok(())

} ```
