Enum `ErrorKind`

#[non_exhaustive]
pub enum ErrorKind

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

This error type is marked as non_exhaustive. This means that adding a new variant is not considered a breaking change.

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 utf8 was enabled.
InvalidLineTerminator: This error occurs when one uses a non-ASCII byte for a line terminator, but where Unicode mode is enabled and UTF-8 mode is 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.
