Planned This feature is planned but not yet implemented.
Feature: Profile meta-type not implemented
Code
// Test profile meta-type - performance profiling with timing
// Shows profiling metadata capture with runtime timestamps
const std = @import("std");
~import std/taps
~event hello {}
~event goodbye {}
~[comptime|runtime] event profiler { source: []const u8, branch: []const u8, destination: ?[]const u8, timestamp_ns: i128 }
~proc hello|zig {
std.debug.print("Hello executed\n", .{});
}
~proc goodbye|zig {
std.debug.print("Goodbye executed\n", .{});
}
~proc profiler|zig {
if (destination) |dest| {
std.debug.print("Profile: {s}.{s} -> {s} @ {}\n", .{source, branch, dest, timestamp_ns});
} else {
std.debug.print("Profile: {s}.{s} -> terminal @ {}\n", .{source, branch, timestamp_ns});
}
}
// Universal tap using profile meta-type
// Captures source event, branch, destination, and runtime timestamp
// NOTE: Profile uses string-based fields (no enum conversion needed)
~tap(* -> *)
