Struct regex_automata::dfa::onepass::BuildError

pub struct BuildError {
    kind: BuildErrorKind,
}

An error that occurred during the construction of a one-pass DFA.

This error does not provide many introspection capabilities. There are generally only two things you can do with it:

• Obtain a human readable message via its std::fmt::Display impl.
• Access an underlying thompson::BuildError type from its source method via the std::error::Error trait. This error only occurs when using convenience routines for building a one-pass DFA directly from a pattern string.

When the std feature is enabled, this implements the std::error::Error trait.

Trait Implementations

impl Clone for BuildError

fn clone(&self) -> BuildError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

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.
