tpt-zero-text

The Structural Layer of the tpt-zero-* ecosystem: robust, zero-external-dependency data structures, text processing, and mathematical primitives that scale from core to alloc to std via feature flags.

Every crate in this workspace is #![no_std] by default (a core-only build with zero external production dependencies) and gains String/Vec-returning convenience APIs behind an opt-in alloc feature. Intra-workspace crates may depend on each other (e.g. tpt-zero-matrix depends on tpt-zero-vec), but nothing in this workspace ever pulls in a dependency from outside the tpt-zero-* family.

Target audience: WASM developers, game developers, IoT application writers, and developers building configuration-driven no_std systems.

Crates

Every crate was reviewed against the existing crates.io ecosystem before release. Crates that would just be a redundant clone of an established no_std incumbent (e.g. arrayvec, spin, percent-encoding, csv-core) were kept in the repo as internal/reference implementations but renamed from the tpt-zero- prefix to out-zero- and marked publish = false, so publish intent is visible at a glance from the crate name alone. See TODO.md for the full per-crate rationale.

Published (tpt-zero-*)

Tier	Crate	Purpose
0	tpt-zero-utf8	UTF-8 validation, char-boundary finding, safe scalar iteration
0	tpt-zero-numstr	Integer/float to string conversion and back
0	tpt-zero-str-search	Fast byte/substring search algorithms
0	tpt-zero-fast-math	Approximate sqrt/sin/cos/tan via lookup tables
0	tpt-zero-channel	Lock-free bounded MPSC queue
0	tpt-zero-color	RGB/RGBA/HSV conversions and hex parsing
1	tpt-zero-slug	URL-safe string slug normalization
1	tpt-zero-glob	Glob pattern matching
1	tpt-zero-json	Pull-based, zero-allocation JSON tokenizer/parser
1	tpt-zero-vec	2D/3D/4D vector math with operator overloading
2	tpt-zero-matrix	3x3 and 4x4 matrix transformations
2	tpt-zero-quat	Quaternions for 3D rotation

Internal / not published (out-zero-*)

Fully implemented and tested, but publish = false — kept for internal use and as a reference implementation. Each crate's README names the crates.io incumbent it was judged redundant with.

Tier	Crate	Purpose
0	out-zero-arrayvec	Vec-like structure backed by a fixed-size array
0	out-zero-ring	Fixed-capacity circular buffer
0	out-zero-intrusive	Intrusive doubly-linked lists
0	out-zero-once	no_std lazy initialization / run-once logic
0	out-zero-spin	Spinlock-based mutex/rwlock for no_std
1	out-zero-arraystring	String-like structure backed by a fixed-size array
1	out-zero-linear-map	Sorted-array-backed map for small datasets
1	out-zero-pool	Object pool to reuse allocations
1	out-zero-url-encode	Percent-encoding and decoding
1	out-zero-xml-escape	XML/HTML entity escaping and unescaping
1	out-zero-csv	Iterator-based, RFC 4180 compliant CSV parsing
1	out-zero-toml-lite	Restricted, safe TOML parser
1	out-zero-ini	Simple INI configuration file parsing
