SSE API

Server-Sent Events parsing and streaming (src/web/sse/).

Parser (httpx.sse.Parser)

Member	Description
Event	Parsed event: eventType, data, id, retryMs
EventParser	Stateful WHATWG stream parser

var parser = httpx.sse.Parser.EventParser.init(allocator);
defer parser.deinit();
// feed chunks, drain parser.next() for Event values

Writer (httpx.sse.Writer)

httpx.sse.Writer.EventWriter builds SSE payloads in handlers:

var out = std.ArrayList(u8).empty;
var writer = httpx.sse.Writer.EventWriter.init(ctx.allocator);
try writer.writeEvent(&out, &[_][]const u8{"payload"}, "message", 1, null);
return .{ .status = 200, .body = out.items, .contentType = "text/event-stream; charset=utf-8" };
