Struct regex_automata::hybrid::BuildError
source · pub struct BuildError {
kind: BuildErrorKind,
}
Expand description
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 itssource
method via thestd::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.
