The kind of an error that can occur.
An error that occurred as a result of parsing a regular expression. This can be a syntax error or an error that results from attempting to compile a regular expression that is too big.
The string here is the underlying error converted to a string.
An error that occurs when a building a regex that isn't permitted to
match a line terminator. In general, building the regex will do its
best to make matching a line terminator impossible (e.g., by removing
\n from the
\s character class), but if the regex contains a
\n literal, then there is no reasonable choice that can be made and
therefore an error is reported.
The string is the literal sequence found in the regex that is not allowed.
This error occurs when a non-ASCII line terminator was provided.
The invalid byte is included in this error.
