Extends AsyncWrite with methods for writing numbers.

Most of the methods defined here have an unconstrained type parameter that must be explicitly instantiated. Typically, it is instantiated with either the BigEndian or LittleEndian types defined in this crate.

Examples

Write unsigned 16 bit big-endian integers to a [Write]:

use tokio_byteorder::{BigEndian, AsyncWriteBytesExt};

#[tokio::main]
async fn main() {
    let mut wtr = vec![];
    wtr.write_u16::<BigEndian>(517).await.unwrap();
    wtr.write_u16::<BigEndian>(768).await.unwrap();
    assert_eq!(wtr, vec![2, 5, 3, 0]);
}

Provided methods

fn write_u8<'a>(&'a mut self, n: u8) -> WriteU8<&'a mut Self> where
    Self: Unpin

Writes an unsigned 8 bit integer to the underlying writer.

Note that since this writes a single byte, no byte order conversions are used. It is included for completeness.

Errors

This method returns the same errors as Write::write_all.

Examples

Write unsigned 8 bit integers to a Write:

use tokio_byteorder::{AsyncWriteBytesExt};

#[tokio::main]
async fn main() {
    let mut wtr = Vec::new();
    wtr.write_u8(2).await.unwrap();
    wtr.write_u8(5).await.unwrap();
    assert_eq!(wtr, b"\x02\x05");
}

fn write_i8<'a>(&'a mut self, n: i8) -> WriteI8<&'a mut Self> where
