Crate write_into

Defines a trait built on top of io::Write to write things into it.

use std::io;

trait WriteInto {
    type Output;
    fn write_into(self, sink: &mut impl io::Write) -> io::Result<Self::Output>;
}

The crate also provides wrappers, such as BigEndian and LittleEndian, to write values in particular formats.

Example

use write_into::{BigEndian, write_into};

let mut buffer = Vec::new();
write_into(&mut buffer, BigEndian(0xCAFEBABEu32)).unwrap();
assert_eq!(&buffer, &[0xCA, 0xFE, 0xBA, 0xBE]);

Structs

BigEndian

Used to write values in big endian byte order.

LittleEndian

Used to write values in little endian byte order.

Plain

Used to write values as they are represented in memory.

Sequence

Used to write values from IntoIterator.

SizedSequence

Used to write values from IntoIterator with known size.

Sleb128

Used to write values in LEB-128 format (signed).

Uleb128

Used to write values in LEB-128 format (unsigned).

Traits

WriteInto

Writes value into I/O sink.

Functions

align_position

Aligns position in the I/O sink to the given boundary and returns a new position.

write_into

An alias for WriteInto::write_into for writing write_into(sink, Wrapper(...)) instead of Wrapper(...).write_into(sink).
