Function bin_io::utils::skip

pub fn skip<R: Read, W: Write, Rf, Wf, I>(
    f: (Rf, Wf), 
    i: I
) -> (impl ReadFn<R, ()>, impl WriteFn<W, ()>) where
    Rf: ReadFn<R, I>,
    Wf: WriteFn<W, I>,
    I: Clone, 

Skips a value to a writer/reader.

This is an helper function used in conjuction with seq!.

Reading

The function just reads the value and then discards the value.

Writing

The function writes the input value.

Remarks

This function is identical to bind with the exception that it won't check the read value.

Examples

use std::io::Cursor;
use bin_io::numbers::{ be_u8 };
use bin_io::{ write, skip, seq };
 
let vec = Vec::new();
let mut cursor = Cursor::new(vec);
 
let a = seq!(
    (),
    skip(be_u8(), 0x50) =>
);
 
write(&mut cursor, &(), a)
    .unwrap();
 
assert_eq!(cursor.get_ref()[0], 0x50);
