Struct BuildError
pub struct BuildError { /* private fields */ }An error that can occurred during the construction of a thompson NFA.
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::Displayimpl. - Access an underlying
regex_syntax::Errortype from itssourcemethod via thestd::error::Errortrait. This error only occurs when using convenience routines for building an NFA directly from a pattern string.
Otherwise, errors typically occur when a limit has been breached. For
example, if the total heap usage of the compiled NFA exceeds the limit
set by Config::nfa_size_limit, then
building the NFA will fail.
Implementations
impl BuildError
fn size_limit(&self) -> Option<usize>If this error occurred because the NFA exceeded the configured size limit before being built, then this returns the configured size limit.
The limit returned is what was configured, and corresponds to the maximum amount of heap usage in bytes.
