HTTP/3 Client Runtime Example

End-to-end HTTP/3 with the high-level client runtime (.http3 = true). See examples/http3Client.zig.

zig

var client = httpx.Client.init(allocator, io, .{
    .http3 = true,
});
defer client.deinit();

var response = try client.get(url, .{ .httpVersion = .http3 });
defer response.deinit();
std.debug.print("status={d}\n", .{response.status});

Expected Output

text

status=200

Status is 200 on success against the loopback HTTP/3 endpoint; URL/port vary per run.

Run

bash

zig build run-http3-client

What to Verify

Control-stream SETTINGS exchange validates.
The client decodes HTTP/3 HEADERS/DATA frames into a standard Response.
