`Equatable` conformance will not compile – `ARTErrorInfo` is not `Equatable`

[maratal]

DiscontinuityEvent declares Equatable, yet the stored property ARTErrorInfo coming from Ably Cocoa does not conform to Equatable.
Compilation will therefore fail with “Type ‘ARTErrorInfo’ does not conform to protocol ‘Equatable’”.

Two ways forward:

-public struct DiscontinuityEvent: Sendable, Equatable {
+public struct DiscontinuityEvent: Sendable {

or keep Equatable and provide a manual implementation (comparing the few stable fields you care about, e.g. code + message). Removing the conformance is usually safer because ARTErrorInfo also lacks Sendable, so you might need @unchecked Sendable too.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

public struct DiscontinuityEvent: Sendable {
    /// The error associated with this discontinuity.
    public var error: ARTErrorInfo

    public init(error: ARTErrorInfo) {
        self.error = error
    }
}

In Sources/AblyChat/Discontinuity.swift around lines 3 to 10, the struct
DiscontinuityEvent declares Equatable conformance but its stored property
ARTErrorInfo does not conform to Equatable, causing a compilation error. To fix
this, either remove the Equatable conformance from DiscontinuityEvent or
implement a custom Equatable conformance manually by comparing selected stable
fields of ARTErrorInfo such as code and message. Also consider removing or
adjusting Sendable conformance accordingly.
