Struct Writer 

pub struct Writer { /* private fields */ }

Writing cursor building an outgoing buffer.

Implementations

impl Writer

pub fn new(base: usize) -> Self

New writer whose first byte will sit at absolute frame offset base (needed for Unicode parity padding decisions).

pub fn len(&self) -> usize

Number of bytes written so far.

pub fn is_empty(&self) -> bool

True when nothing has been written yet.

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

Borrow the accumulated bytes.

pub fn raw(&mut self, data: &[u8])

Append raw bytes.

pub fn push(&mut self, v: u8)

Append one byte.

pub fn push_u16(&mut self, v: u16)

Append a little-endian u16.

pub fn push_u32(&mut self, v: u32)

Append a little-endian u32.

pub fn push_u64(&mut self, v: u64)

Append a little-endian u64.

pub fn pad_to_parity(&mut self)

Insert a pad byte so the current position becomes even relative to Self::base (Unicode alignment requirement).

pub fn zstring(&mut self, s: &str, unicode: bool)

Append a NUL-terminated string honouring the Unicode flag.

Trait Implementations

impl Debug for Writer

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

Formats the value using the given formatter.

impl Default for Writer

fn default() -> Writer

Returns the “default value” for a type.
