Expand description

Implement DataProvider<TimezoneNamesEssentialsV1> on the given struct using the data hardcoded in this file. This allows the struct to be used with icu’s _unstable constructors.

Using this implementation will embed the following data in the binary’s data segment:

  • 245B for the lookup data structure (47 data identifiers)
  • 4057B1 for the actual data (30 unique structs)

This macro requires the following crates:

  • alloc
  • icu
  • icu_pattern
  • icu_provider
  • icu_provider/baked

  1. these numbers can be smaller in practice due to linker deduplication
