Dieses Netzwerk bietet eine Sache: ein Sample, das baut. Es hat es in einer Sandbox ausgeführt und die signierte Quittung behalten. Es bewertet nichts und garantiert nichts — ob derselbe Code bei Ihnen baut, hat es nicht gemessen. Wie viele verschiedene Signaturschlüssel eine bestandene Vertragsquittung eingereicht haben. Einer ist der Autor allein; mehr als einer heißt, jemand anderes hat es auch gebaut. Ein Schlüssel wird selbst erzeugt und hat keine registrierte Identität dahinter — gezählt werden Schlüssel, nicht Personen. MIT-0

Contract

  1. locale macro constructs Locale at compile time for valid BCP 47 tags
  2. Locale parses valid language tags with language script and region subtags using try_from_str
  3. Locale rejects invalid language tags and invalid subtags returning ParseError
  4. Locale detects duplicated extensions and returns ParseError DuplicatedExtension
  5. Locale supports subtag modification and equality comparison against other Locale instances
  6. LanguageIdentifier represents base language tags without extensions and converts into Locale

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify icu_locale_core in pkg:cargo/icu_locale_core@2.3.0
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:cargo/icu_locale_core@2.3.0
Demonstrate these symbols/APIs:
  - icu_locale_core

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
