donner::editor::sandbox::WireWriter Class Reference

Append-only byte buffer writer. Cheap by design — a std::vector<uint8_t> owner with a few typed helpers. No growth policy beyond the vector's. More...

#include "donner/editor/sandbox/Wire.h"

Classes
struct	MessageToken
	Reserves a payload-length slot before the payload is encoded, returning a token the caller hands back to finishMessage() once the payload is complete. This avoids having to buffer the payload twice. More...

Public Member Functions
std::size_t	size () const
	Total bytes written so far.
std::span< const uint8_t >	data () const
	Returns a view of the accumulated bytes.
std::vector< uint8_t >	take () &&
	Releases ownership of the accumulated bytes.
void	writeMessageHeader (Opcode opcode, uint32_t payloadLength)
	Writes a raw message header: u32 opcode, u32 payload_length. The caller is responsible for appending payload_length bytes immediately after.
MessageToken	beginMessage (Opcode opcode)
void	finishMessage (MessageToken token)
Primitives
All writes are little-endian.
void	writeU8 (uint8_t v)
void	writeU32 (uint32_t v)
void	writeI32 (int32_t v)
void	writeU64 (uint64_t v)
void	writeF64 (double v)
void	writeBool (bool v)
void	writeBytes (std::span< const uint8_t > bytes)
void	writeString (std::string_view s)

Detailed Description

Append-only byte buffer writer. Cheap by design — a std::vector<uint8_t> owner with a few typed helpers. No growth policy beyond the vector's.
