GAIA_NODISCARD bool	valid () const noexcept

Public Attributes
void *	data = nullptr
	Raw component payload bytes. Null for tags and invalid views.
uint32_t	size = 0
	Payload size in bytes.
uint32_t	flags = ComponentRawViewFlag_None
	Bitmask of ComponentRawViewFlags values.

Detailed Description

Non-owning mutable view over raw component bytes on an entity.

The view intentionally stores only a pointer, byte size, and flags. The component id is omitted because callers already pass it to World::mut_raw(...); keeping it out of the view keeps the return value compact. A valid tag is represented by data == nullptr, size == 0, and ComponentRawViewFlag_Valid set.

Note

Treat the view as a short-lived borrow. Structural changes can invalidate data.

mut_raw(...) is a silent mutation path. Call World::modify_raw(...) after writing through data directly. ComponentCursor::write_bytes() finishes the root component write itself.
