Struct Writer 

pub struct Writer { /* private fields */ }

Output builder with a byte budget; integer ranges are enforced by Rust types.

Implementations

impl Writer

pub fn new(maximum: usize) -> Self

Construct a writer with a maximum encoded length.

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

Append bytes without exceeding the configured budget.

pub fn u8(&mut self, value: u8) -> Result<()>

Write an unsigned byte.

pub fn i8(&mut self, value: i8) -> Result<()>

Write a signed byte.

pub fn u16(&mut self, value: u16) -> Result<()>

Write an unsigned 16-bit word.

pub fn i16(&mut self, value: i16) -> Result<()>

Write a signed 16-bit word.

pub fn u32(&mut self, value: u32) -> Result<()>

Write an unsigned word or original f32 bits.

pub fn i32(&mut self, value: i32) -> Result<()>

Write a signed 32-bit word.

pub fn f32(&mut self, value: f32) -> Result<()>

Write an IEEE-754 single-precision value.

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

Write a length-prefixed original or newly encoded string.

pub fn finish(self) -> Vec<u8>

Consume the writer and return its bytes.
