Detailed Description

A generic buffer structure for string printing and parsing strings.

Because doing manual length checks is error prone and a waste of everyones time.

char const *	name	Name for rule set to aid we debugging.
bool	skip[UINT8_MAX+1]	Characters that are escaped, but left in the output along with the escape character. This is useful where we need to interpret escape sequences for parsing, but where the string will be passed off to a 3rd party library which will need to interpret the same sequences.
char	subs[UINT8_MAX+1]	Special characters and their substitutions. Indexed by the printable representation i.e. 'n' for .

◆ fr_slen_t

typedef ssize_t fr_slen_t

Represents number of bytes parsed or location of parse error.

Number of bytes parsed will be >= 0.

If a parse error occurs the value will be the negative offset of the error -1. i.e. offset 0 will be -1.

This is to disambiguate between 0 bytes parsed and error at offset 0.
