Struct dhcproto::encoder::Encoder

pub struct Encoder<'a> { /* private fields */ }

Encoder type, holds a mut ref to a buffer that it will write data to and an offset of the next position to write

Implementations

impl<'a> Encoder<'a>

pub fn new(buffer: &'a mut Vec<u8>) -> Self

Create a new Encoder from a mutable buffer

pub fn buffer(&self) -> &[u8]

Get a reference to the underlying buffer

pub fn write_slice(&mut self, bytes: &[u8]) -> EncodeResult<()>

write bytes to buffer Return: number of bytes written

pub fn write<const N: usize>(&mut self, bytes: [u8; N]) -> EncodeResult<()>

Write const number of bytes to buffer

pub fn write_u8(&mut self, data: u8) -> EncodeResult<()>

write a u8

pub fn write_u16(&mut self, data: u16) -> EncodeResult<()>

write a u16

pub fn write_u32(&mut self, data: u32) -> EncodeResult<()>

write a u32

pub fn write_u128(&mut self, data: u128) -> EncodeResult<()>

write a u128

pub fn write_u64(&mut self, data: u64) -> EncodeResult<()>

write a u64

pub fn write_i32(&mut self, data: i32) -> EncodeResult<()>

write a i32

pub fn write_fill_bytes( &mut self, bytes: &[u8], fill_len: usize ) -> EncodeResult<()>

Writes bytes to buffer and pads with 0 bytes up to some fill_len

Returns Err - if bytes.len() is greater then fill_len

pub fn write_fill<T: AsRef<[u8]>>( &mut self, s: &Option<T>, fill_len: usize ) -> EncodeResult<()>

Writes value to buffer and pads with 0 bytes up to some fill_len if String is None then write fill_len 0 bytes

Returns Err - if bytes.len() is greater then fill_len

impl<'a> Debug for Encoder<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
