Struct `UnicodeWordBoundaryError`

pub struct UnicodeWordBoundaryError(/* private field */);

An error that occurs when the Unicode-aware \w class is unavailable.

This error can occur when the data tables necessary for the Unicode aware Perl character class \w are unavailable. The \w class is used to determine whether a codepoint is considered a word character or not when determining whether a Unicode aware \b (or \B) matches at a particular position.

This error can only occur when the unicode-word-boundary feature is disabled.
