Type Alias: UnpairedEscapeSink
UnpairedEscapeSink = () =>
void
A callback the codec calls when it encounters an escape character that does not
head a three-character escape sequence. The character is preserved verbatim as a
literal; the callback lets the parser surface a value-free
ASTM_UNPAIRED_ESCAPE_CHARACTER warning. Optional so the codec can be used purely.
Returns
void
