Enums

enum class chunk_type : std::uint8_t

Values:

enumerator chunk_type_index

enumerator chunk_type_const_pointer

enumerator chunk_type_pointer

Functions

constexpr serialization_chunk create_index_chunk(std::size_t index, std::size_t size) noexcept

constexpr serialization_chunk create_const_pointer_chunk(void const *pos, std::size_t size) noexcept

Zero-copy chunk referring to immutable caller-owned memory (save path). Parcelports must treat this like chunk_type_pointer for transmission.

constexpr serialization_chunk create_pointer_chunk(void *pos, std::size_t size) noexcept

Zero-copy chunk referring to mutable memory (typically receive path).

constexpr serialization_chunk create_pointer_chunk(void const *pos, std::size_t size) noexcept

Backward-compatible overload for const storage; same as create_const_pointer_chunk.

constexpr serialization_chunk create_pointer_chunk(std::nullptr_t, std::size_t size) noexcept

Create a mutable-pointer chunk with a null address.

struct serialization_chunk

Public Functions

inline constexpr void const *data() const noexcept

Active union member depends on type_: use this for both pointer kinds (mutable storage is returned as void const*).

inline constexpr void *data() noexcept

Mutable view; only valid for chunk_type_pointer chunks.

inline constexpr std::size_t size() const noexcept
