Expand description

Implement DataProvider<ExemplarCitiesV1> 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:

  • 840B for the lookup data structure (161 data identifiers)
  • 248266B1 for the actual data (146 unique structs)

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