cuid v1.3.3, cuid2 v0.1.3

cuid2 v0.1.3, cuid 1.3.3

Upcoming

• The next major release will be a breaking release, dropping the
  top-level cuid(), slug(), and is_cuid() functions in favor of
  their version-specific counterparts (see below).
• I also intend to split the v1 CUID functionality out into its own
  crate and publish it independently, like I have done for cuid2.
  The top-level cuid crate will then pull in the sub-crates depending
  on features, making it easy to just pull the CUID version you need.

Added

• Provide new top-level functions from the cuid library to disambiguate
  CUID versions:
  • cuid::cuid1(): generate a v1 CUID, replacement for deprecated cuid()
  • cuid::cuid1_slug(): generate a v1 CUID slug, replacement for deprecated slug()
  • cuid::is_cuid1() - check whether a string looks like it could be a v1 CUID,
    replacement for deprecated is_cuid()
  • cuid::is_cuid1_slug() - check whether a string looks like it could be a v1 CUID
    slug, replacement for deprecated is_cuid()
  • cuid::cuid2_slug() - generate a v2 CUID of length 10
  • cuid::is_cuid2_slug() - check whether a string looks like could be a v2 CUID
    slug
  • cuid::Cuid2Constructor - expose the v2 CUID constructor interface
• Added a couple of functions to cuid2 for parity with v1 functions:
  • cuid2::slug() - generate a v2 CUID of length 10
  • cuid2::is_slug() - check whether a string looks like could be a v2 CUID
    slug
• Added support for webassembly builds. Builds are tested for wasm32-unknown-unknown
  and wasm32-wasi targets. I intend to add Javascript bindings and publish
  npm packages in an upcoming update.
  • The system hostname is not available to WASM, so for the CUID v1
    fingerprint algorithm, we instead use a v4 UUID. This does mean the
    fingerprint will not be consistent on a host over time, which slightly
    diverges from the behavior of CUIDs on other targets. Please open an
    issue if this is a problem for you.

Changed

• CUID v1 functions are no longer marked as deprecated. The original JS
  library was marked as insecure and deprecated by its creators, but this
  was merely due to their personal stance that any k-sortable IDs are
  insecure and should not be used. This library's author does not share
  the same view. New functions have been provided to better disambiguate
  creating v1 vs v2 IDs, and functions that do not explicitly specify
  a version are still marked as deprecated.
• The CUID binaries now randomize the counter prior to generating an ID,
  rather than always starting at 0. This ensures that commandline-generated
  CUIDs do not lose entropy relative to library-generated CUIDs due to
  always having the same counter value.
• The cuid2::is_cuid()/cuid::is_cuid2() function has been improved and
  now rejects more strings that are invalid CUIDs (contribution by @stormshield-kg)
• The cuid2 binary now supports an optional --length|-l argument, which
  enables specifying the length of the generated CUID (contribution by @der-fruhling)

Removed

• Removed old benchmarks and #[cfg(nightly)] blocks. Criterion benchmarks
  are the important ones, and those remain.
