Struct Writer 

pub struct Writer { /* private fields */ }

Append-only byte writer.

Implementations

impl Writer

pub fn new() -> Self

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

pub fn u8(&mut self, v: u8) -> &mut Self

pub fn u16(&mut self, v: u16) -> &mut Self

pub fn u32(&mut self, v: u32) -> &mut Self

pub fn u64(&mut self, v: u64) -> &mut Self

pub fn i64(&mut self, v: i64) -> &mut Self

pub fn bool(&mut self, v: bool) -> &mut Self

pub fn bytes(&mut self, v: &[u8]) -> &mut Self

Length-prefixed bytes. The payload is copied verbatim — no escaping, no separator scan, so any byte sequence survives.

pub fn str(&mut self, v: &str) -> &mut Self

pub fn opt_str(&mut self, v: Option<&str>) -> &mut Self

None and Some("") differ by the tag byte, not by length.

pub fn opt_bytes(&mut self, v: Option<&[u8]>) -> &mut Self

Trait Implementations

impl Default for Writer

fn default() -> Writer

Returns the “default value” for a type.
