Should TimeZoneIdMapper support efficient storage and retrieval of non-canonical IANA IDs?

9

See https://github.com/unicode-org/icu4x/issues/5533#issuecomment-2380240259 Currently, TimeZoneIdMapper has two data payloads: 1. Trie: IANA string to BCP-47 ID (does NOT support random access: only key-to-value lookup) 2. Map: BCP-47 ID to canonical IANA...

Generic Partial Location

Generic Partial Location is supposed to be used when the offsets for a zone are ambiguous. There isn't a clear algorithm in the spec on how to determine this, but...

Implement MessageFormat

I couldn't find an issue to track the ICU4X implementation of MessageFormat, so I'm making one now. We should implement MF2 syntax, of course, but we also will likely want...

Make VarZeroVec branchless like ZeroVec

1

As discussed in https://github.com/unicode-org/icu4x/pull/5434#issuecomment-2332128845 To start, we should make VarZeroVec have private fields in 2.0. The actual optimization can be done later.

Evaluate consistency and naming of char vs u32 methods in icu_collections and icu_properties

11

We inconsistently name methods in the various properties and collections classes that deal with char vs u32. Examples: `contains(char)`, `contains_32(u32)`, `get(char)`, and `get_u32(u32)`, but sometimes it is `get(u32)`. And the...

Reaffirm TryWriteable design

11

From https://github.com/unicode-org/icu4x/pull/5493 We previously made two design decisions about TryWriteable that might be worth revisiting before 2.0: 1. TryWriteable and Writeable are not implemented at the same time 2. TryWriteable...

Remove Default impls that load data

17

Currently we have a number of `impl Default` on classes that have a `new()` function that load data. The data is usually singleton but doesn't need to be (see SentenceSegmenter...

Do something with legacy skeleton datetime APIs

Currently they are behind the `feature = "datagen"` flag in icu_datetime. What should we do with them? 1. Leave as-is, potentially with a bit of documentation. Question: does `feature =...
