Struct GroupInfoError

pub struct GroupInfoError { /* private fields */ }

Available on crate feature alloc only.

An error that may occur when building a GroupInfo.

Building a GroupInfo does a variety of checks to make sure the capturing groups satisfy a number of invariants. This includes, but is not limited to, ensuring that the first capturing group is unnamed and that there are no duplicate capture groups for a specific pattern.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for GroupInfoError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
