Crate ere_core 

This crate provides the core functionality to the ere crate.

Modules

config

fixed_offset

This is a highly-efficient implementation for regexes where capture groups always have the same offset and the same length (in bytes). This also means the text has a fixed length.

nfa_static

Implements a version of WorkingNFA that can be serialized statically into a binary.

one_pass_u8

This implements an engine for one-pass regexes.

parse_tree

Implements the ERE parser and primitive types (like Atom).

pike_vm

Not exactly the PikeVM, but close enough that I am naming it that. It works similarly, except that since we are building at compile-time, there are benefits from inlining splitting.

pike_vm_u8

Implements a Pike VM-like regex engine for u8s.

simplified_tree

Implements a simplified intermediate representation of a regular expression.

visualization

Implements visualization features for NFAs. Typically not used outside debug.

working_nfa

Implements the primary compile-time intermediate WorkingNFA structure for optimization.

working_u8_nfa

Implements u8-based version of crate::working_nfa.

Structs

Regex

A regular expression (specifically, a POSIX ERE).

Functions

Always uses the one_pass_u8

__compile_regex_engine_pike_vm

Always uses the pike_vm engine

__compile_regex_engine_pike_vm_u8
