Module engine 

Engine module - coordinates regex execution.

Selects the optimal execution strategy based on pattern properties.

Structs

Capabilities

Runtime capabilities.

CompiledRegex

A compiled regex ready for execution.

Enums

EngineType

The selected engine type.

Functions

compile

Compiles an NFA into an executable regex (legacy API). Note: This cannot use Shift-Or as it requires HIR for Glushkov construction. Also cannot use prefilter (requires HIR for literal extraction).

compile_from_hir

Compiles an HIR into an executable regex. This is the preferred API as it can use Shift-Or for small patterns and prefilters for SIMD-accelerated candidate detection.

compile_with_jit

Compiles an HIR with JIT compilation for maximum performance.

compile_with_pikevm

Compiles an HIR using PikeVM (default, no JIT).

select_engine

Selects the optimal engine for a given NFA (legacy API). Note: For Shift-Or selection, use select_engine_from_hir instead.

select_engine_from_hir

Selects the optimal engine for a given HIR. This is the preferred API as it can properly evaluate Shift-Or compatibility using Glushkov construction.
