Vex Standard Library

The Vex Standard Library (std) provides a set of highly optimized, parallelism-first modules to help you build fast, reliable systems. It is written completely in Vex, making use of Vex's powerful Memory Management (VUMM), Tensor / Vectorization types, and compiler-level built-ins to extract maximum performance from the CPU and GPU.

Core Modules

Module	Description
bit	Bitwise manipulation, population counts, masking, leading/trailing zero counts mapped directly to hardware vector intrinsics.
cli	Subcommand, argument, and flag parsing utilities for rapid CLI application development.
compress	Pure Vex DEFLATE and GZIP compression and decompression paths optimized for the vectorizer.
crypto	Core cryptographic algorithms and checksums (e.g. CRC32, AES, MD5) leveraging crypto SIMD instructions (AES-NI) with software fallbacks.
db	Database connections, async pooling, and Native PostgreSQL bindings written purely in Vex without C driver dependencies.
fs	Buffered asynchronous and synchronous File System operations integrated into the Vex M:N scheduler.
hash	Extremely fast, non-cryptographic hashing algorithms (FNV-1a, xxHash3, WyHash) optimized for Hash Maps and general probing.
http	Zero-allocation HTTP/1.1 Protocol parsers and baseline Web Server constructs.
inference	LLM specific primitive abstractions. Holds logic for RoPE, K/V Cache, and Hardware quantizations.
io	Basic cross-platform I/O streams and file descriptors.
math	Math operations ranging from basic arithmetic to advanced trigonometry. Built with GPU graph fn infrastructure for bulk operations.
ml	High performance Neural Network blocks (RMSNorm, Softmax) executed via Graph blocks.
net	Asynchronous TCP/UDP networking sockets mapped natively to the Vex M:N scheduler loop.
regex	SIMD-Accelerated zero-copy regex engine compiling to bytecode NFAs.
semver	Semantic Versioning definitions and query engines.
serde	A powerful, zero-copy serialization/deserialization framework supporting JSON, TOML, CSV, and MessagePack formats.
strings	String building utilities centered on StringBuilder.
time	Instant OS monotonic hardware clocks without GC pauses.
unicode	Unicode character properties, case folding, and character matching. Powered by binary-searched precompiled tables.
url	Extremely fast, WHATWG-compliant URL parsing and encoding, designed to aggressively reduce small allocations.

Philosophy

The Vex Standard Library follows a few central design pillars:

1. Zero-Copy & Low Allocation: Functions prefer slices (Span<T>), byte buffers (RawBuf), and minimal heap allocations.
2. "Silicon-Ready" Operations: Wherever there are SIMD instructions or potential for parallelism (hashes, loops, string escapes), the std structures it so vex-compiler can vectorize it directly.
3. Extensibility: Things like Serde are abstracted via contracts, bringing familiar ergonomic usage to a completely custom systems stack.
