Source

Expand description

Parse a user-supplied delimiter string into a single byte.

Accepts:

  • a single ASCII character (e.g. ",", "|", ";")
  • the two-character escapes "\t", "\n", "\r" (typing literal tabs in SQL strings or shell args is awkward, so this is the canonical form)

Rejects multi-character strings, non-ASCII, and empty strings with a clear error. Caller is expected to wrap the error with context if needed.
