Swift encourages the use of descriptive names instead of single letters. From the Swift book:

In most cases, type parameters have descriptive names, such as Key and Value in Dictionary<Key, Value> and Element in Array, which tells the reader about the relationship between the type parameter and the generic type or function it’s used in. However, when there isn’t a meaningful relationship between them, it’s traditional to name them using single letters such as T, U, and V, such as T in the swapTwoValues(::) function above.

So I've used my judgement here a bit and renamed some things and left some as single letters.

Summary by CodeRabbit

  • Style
    • Updated generic parameter names throughout the codebase for improved clarity and consistency. No changes to functionality or behavior.

Walkthrough

This update systematically renames generic type parameters across multiple files for improved clarity and consistency. Specifically, generic placeholders such as T are replaced with more descriptive names like Item, Element, Underlying, or Value in protocols, classes, property wrappers, and initializers. The changes affect both source and test code, including mock implementations and documentation comments. No logic, control flow, or error handling is altered; the modifications are strictly limited to type parameter naming.

Changes

File(s) Change Summary
Example/AblyChatExample/Mocks/Misc.swift Renamed typealias and all references from T to Item in MockMessagesPaginatedResult.
Example/AblyChatExample/Mocks/MockSubscription.swift Renamed class generic parameter from T to Element in MockSubscription.
Sources/AblyChat/BufferingPolicy.swift Renamed generic parameter from T to Element in documentation and method signature.
Sources/AblyChat/Messages.swift Renamed generic parameter from T to Underlying in public initializer of MessageSubscription.
Sources/AblyChat/PaginatedResult.swift Renamed generic parameter from T to Item throughout PaginatedResult protocol, PaginatedResultWrapper, and related methods.
Sources/AblyChat/Subscription.swift Renamed generic parameter from T to Underlying in initializers of AnyNonThrowingAsyncSequence and Subscription.
Tests/AblyChatTests/Helpers/SynchronizedAccess.swift Renamed generic parameter from T to Value in SynchronizedAccess property wrapper and all related declarations.
Tests/AblyChatTests/MessageSubscriptionTests.swift Renamed generic parameter from T to Item in MockPaginatedResult and all related references.

Poem

In fields of code where generics hop,
"T" becomes "Item,"—a naming swap!
"Element" and "Value" join the spring,
Clarity blooms, let the type names sing.
A rabbit's delight, so clear and neat,
Consistent names make code a treat! 🐇✨

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
