Functions

Function	Description
`_ss_byte_at`
`_ss_copy`
`ss_new`	Create new scanner over source string.
`ss_scan`	Try to match pattern at current position. If found, advance and return 1.
`ss_check`	Check if pattern matches at current position without advancing.
`ss_skip`	Advance position by n bytes.
`ss_skip_until`	Skip forward until pattern is found. Returns distance skipped, -1 if not found.
`ss_rest`	Copy remaining unscanned portion to out. Returns length.
`ss_rest_len`	Length of remaining unscanned portion.
`ss_eos`	1 if at end of string.
`ss_pos`	Current scan position.
`ss_reset`	Reset scanner to beginning.
`ss_matched`	Copy last matched string to out. Returns length.
`ss_peek`	Peek at next n bytes without advancing. Returns bytes copied.
`ss_scan_byte`	Read one byte and advance. Returns byte value or -1 at end.
