Errors

Double returning type => no need for specific return structures.

Timer

const Timer = std.time.Timer;
var timer = try Timer.start();
var duration = timer.read() / 1000000; // ns -> ms

var value = db.get(key) orelse return error.notHere;

When the result actually is a single value (anonymous hash). src/switch.zig:125:37: error: binary operator | has whitespace on one side, but not the other. self.db.fetchSwapRemove(fd) |k,v|{
