#[non_exhaustive]
pub enum ErrorKind { Regex(String), NotAllowed(String), InvalidLineTerminator(u8), }
Expand description

The kind of an error that can occur.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Regex(String)

An error that occurred as a result of parsing a regular expression. This can be a syntax error or an error that results from attempting to compile a regular expression that is too big.

The string here is the underlying error converted to a string.

§

NotAllowed(String)

An error that occurs when a building a regex that isn’t permitted to match a line terminator. In general, building the regex will do its best to make matching a line terminator impossible (e.g., by removing \n from the \s character class), but if the regex contains a \n literal, then there is no reasonable choice that can be made and therefore an error is reported.

The string is the literal sequence found in the regex that is not allowed.

§

InvalidLineTerminator(u8)

This error occurs when a non-ASCII line terminator was provided.

The invalid byte is included in this error.
