Batch / Race / AllSettled Concurrent Requests

Demonstrates httpx.all(), httpx.any(), httpx.race(), and httpx.allSettled() for concurrent batch HTTP requests with different settling semantics.

Demo Program

// Build a batch of requests using BatchBuilder
var batch = httpx.BatchBuilder.init(allocator);
defer batch.deinit();
_ = try batch.get(base_url);
_ = try batch.get(base_url);
_ = try batch.get(base_url);

// httpx.all() — wait for every request
const all_results = try httpx.all(allocator, &client, batch.requests.items, .{ .mode = .single_thread });

// httpx.any() — first 2xx response wins
const first_2xx = try httpx.any(allocator, &client, batch.requests.items, .{ .mode = .single_thread });

// httpx.race() — first completion wins (success or error)
var first_done = try httpx.race(allocator, &client, batch.requests.items, .{ .mode = .single_thread });

// httpx.allSettled() — all complete, never throws on individual errors
const settled = try httpx.allSettled(allocator, &client, batch.requests.items, .{ .mode = .single_thread });

Checklist

• [x] httpx.all() returns all results and reports successful count
• [x] httpx.any() returns the first 2xx response (or null)
• [x] httpx.race() returns whichever request finishes first
• [x] httpx.allSettled() returns all outcomes with no thrown errors
• [x] Convenience aliases print: first(), fastest(), settled()
