pub fn compile( &self, input: &str, options: CompileOptions, ) -> (Option<String>, Vec<Diagnostic>)

Compile a Expr that has been parsed, to a regex

pub fn extract_tests(self) -> Vec<Test>

Extracts top-level all unit tests from the Pomsky expression

pub fn extract_tests_ref(&self) -> Vec<&Test>

Extracts top-level all unit tests from the Pomsky expression

pub fn parse_and_compile( input: &str, options: CompileOptions, ) -> (Option<String>, Vec<Diagnostic>, Vec<Test>)

Parse a string to a Expr and compile it to a regex.
