Struct `BuildError`

struct BuildError { ... }

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.
