Data Fields
const uint8_t *	base
	First readable byte of the flat view.
size_t	len
	Readable length in bytes.

Detailed Description

Bounded flat-memory backing for unarch_read_fn.

Describes [base, base + len) as a readable archive. Used by the wrapped-open paths: the unwrapped (decompressed) bytes live in a caller arena and this descriptor re-presents them through the common read seam. The descriptor must out-live every read through it, so callers embed it next to the arena it describes.

Invariant

base addresses at least len readable bytes while any reader holds this descriptor.

Example:

unarch_mem_t mem = {.base = arena, .len = unwrapped_len};
size_t got = unarch_mem_read(&mem, 0U, hdr, sizeof(hdr));
