Struct MessageEncoder 

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

Simplifies encoding data with the Encode trait.

MessageEncoder maintains an internal position within a mutable byte slice akin to std’s Cursor type, allowing sequential writing of multiple encoded values without manually tracking offsets.

Example

let mut buf = [0u8; 16];
let mut enc = MessageEncoder::new(&mut buf);
let value: u16 = 0x1234;
enc.write(&value);
assert_eq!(enc.position(), 2);

Implementations

impl<'a> MessageEncoder<'a>

pub const fn new(data: &'a mut [u8]) -> Self

Creates a new encoder starting at position 0.

pub const fn new_with_position(data: &'a mut [u8], pos: usize) -> Self

Creates a new encoder starting at the given pos.

pub fn write<T: Encode>(&mut self, value: &T)

Encodes a value implementing Encode into the underlying buffer, advancing the current position by value.size().

pub const fn set_position(&mut self, pos: usize)

Sets the current write position.

pub const fn position(&self) -> usize

Returns the current write position.

pub const fn get_ref(&self) -> &[u8]

Returns a reference to the underlying buffer.
