It doesn't need to be, I was cargo-culting the pattern I saw in apple/swift-nio#3229, which added @inlinable to the initializers as well. I presumed that was helping with performance effects from inlining in that code, but I'm replicating that somewhat blindly.

Happy to pull it back out.

init(_ base: Base) { self.base = base }

/// The connection requests got cancelled
public static let requestCancelled = ConnectionPoolError(.requestCancelled)
public static var requestCancelled: Self {
ConnectionPoolError(.requestCancelled)
}
/// The connection requests can't be fulfilled as the pool has already been shutdown
public static let poolShutdown = ConnectionPoolError(.poolShutdown)
public static var poolShutdown: Self {
ConnectionPoolError(.poolShutdown)
}
}
