#include <span.h>

Public Attributes
const uint8_t *	buf
	first byte, or nullptr when there is nothing to read

size_t	len
	readable bytes at buf (0 whenever buf is nullptr)

size_t	pos
	read cursor

bool	err
	sticky: a read ran past len

Detailed Description

A read-only byte region.

Field names match the bytes.h read-cursor convention ({const uint8_t *buf; size_t len; size_t pos; bool err;}), so pc_br_init() / pc_br_take_be() apply unchanged.
