    EmptyClassNotAllowed,

}

The type of an error that occurred while building an Hir.

Variants

UnicodeNotAllowed

This error occurs when a Unicode feature is used when Unicode support is disabled. For example (?-u:\pL) would trigger this error.

InvalidUtf8

This error occurs when translating a pattern that could match a byte sequence that isn't UTF-8 and allow_invalid_utf8 was disabled.

UnicodePropertyNotFound

This occurs when an unrecognized Unicode property name could not be found.

UnicodePropertyValueNotFound

This occurs when an unrecognized Unicode property value could not be found.

UnicodePerlClassNotFound

This occurs when a Unicode-aware Perl character class (\w, \s or \d) could not be found. This can occur when the unicode-perl crate feature is not enabled.

UnicodeCaseUnavailable

This occurs when the Unicode simple case mapping tables are not available, and the regular expression required Unicode aware case insensitivity.

EmptyClassNotAllowed

This occurs when the translator attempts to construct a character class that is empty.

Note that this restriction in the translator may be removed in the future.
