[]

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.
