Struct BuildError 

pub struct BuildError { /* private fields */ }

Available on crate feature hybrid only.

An error that occurs when initial construction of a lazy DFA fails.

A build error can occur when insufficient cache capacity is configured or if something about the NFA is unsupported. (For example, if one attempts to build a lazy DFA without heuristic Unicode support but with an NFA that contains a Unicode word boundary.)

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 nfa::thompson::BuildError type from its source method via the std::error::Error trait. This error only occurs when using convenience routines for building a lazy 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 duplicate 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

Available on crate feature std only.

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

Returns 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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
