Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidLengthGuard(String)

A […] length guard that is malformed or that no run can satisfy.

UnterminatedLengthGuard

A [ length guard with no closing ].

UnterminatedGroupSet

A { group set with no closing }.

EmptyGroupSet

A {} group set with no group names.

UnknownGroupName(String)

A group name that is not a Unicode Joining_Group long name.

TokenAfterTrailingBoundary

A token after the trailing . run boundary.

ExpectedDigitAfterBackslash

A \ in a two-digit priority not followed by a digit.

IncreasingPriority

A two-digit priority whose second digit is greater than its first.

Fields

base: u8

The starting priority.

min: u8

The end priority it drops to.

BackslashWithoutDigit

A \ that does not follow a priority digit.

CaretNotFollowed

A ^ not followed by {, @, or =.

EmptyGroupName

An @ or = with no group name after it.

NoLetters

A pattern line with no letter tokens.

StrayCharacter(char)

A character that is neither pattern syntax nor a joining letter.

ConflictingWeights

Two weights (digits or !) in the same inter-token gap.

WeightOutsideRun

A weight in the gap between a token and a ., where no connection exists.

UnknownImport(String)

A use naming a set that is not built in.
