oxibonsai-core

GGUF parser, quant block types, tensor types, and model configuration for OxiBonsai.

Provides the foundational data types and I/O layer: GGUF file loading (v1/v2/v3), Q1_0_g128 / TQ2_0_g128 (ternary) / Q2_K / Q4_K block deserialization, Qwen3 model configuration, streaming GGUF parser, GGUF writer, model card generation, and all shared error types.

Part of the OxiBonsai project.

Features

• GGUF v1/v2/v3 reader with forward-compatibility layer (gguf::compat)
• GgufStreamParser — state-machine streaming parser for network-loaded models
• GgufWriter — produce valid GGUF byte streams with metadata and tensors
• Qwen3Config — model configuration for Bonsai-8B, 4B, and 1.7B variants
• BlockQ1_0G128 / OneBitTensor — Q1_0_g128 block tensor types
• BlockTQ2_0 / BlockTQ2_0_g128 / TernaryCode — ternary block types
• K-quant formats: BlockQ2K, BlockQ4K
• ModelCard — structured model card (author, license, tags) embedded in GGUF
• mmap feature for zero-copy model file access
• 207 tests passing (unit, integration, fuzz, property)
