Crate oxideshield_guard 

OxideShield Guard Library

Runtime guards and security pipeline for protecting LLM applications.

Guard Tiers

Guards are organized by license tier:

• Community (Free): PatternGuard, LengthGuard, EncodingGuard, PerplexityGuard, PIIGuard, ToxicityGuard, StructuredOutputGuard
• Professional: See oxide-guard-pro crate for SemanticSimilarityGuard, MLClassifierGuard
• Enterprise: Custom guards, private models
