Enum CompileError

#[non_exhaustive]
pub enum CompileError {
    InnerError(BuildError),
    LookBehindNotConst,
    InvalidGroupName,
    InvalidGroupNameBackref(String),
    InvalidBackref,
    NamedBackrefOnly,
}

An error as the result of compiling a regex.

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.

InnerError(BuildError)

Regex crate error

LookBehindNotConst

Look-behind assertion without constant size

InvalidGroupName

Couldn’t parse group name

InvalidGroupNameBackref(String)

Invalid group id in escape sequence

InvalidBackref

Invalid back reference

NamedBackrefOnly

Once named groups are used you cannot refer to groups by number
