26.2.0

This crate is based on VSS (Virtual String System). VSS has been split into two crates:

  • vss_text (this crate): a library for Unicode text processing.
  • vss_extra: libraries for handling JSON, Regexp, XML and other features based on vss_text.

Significant changes are planned in vss_text with the goal to make it a high-quality, high-performance library suitable for a wide range of applications.

The changes include the following (non-exhaustive list):

  • API Changes
    • Introduce an immutable string type.
    • Repurpose the mutable Virtual_String type to a string builder type.
    • Possibly rename the root package VSS to a new more appropriate name. Alire crate, GPR project and repository names might change accordingly.
  • (done) Drop the support of multiple internal encodings in favor of a single internal encoding (likely UTF-8) for improved performance.
