Remove error from error set

[silent snow]

Is there a way I can create a new error set from another error set which excludes a certain error that I have checked for?

if you use a switch, that’s done for you if you do something like

switch (err) {
    error.foo => { … },
    error.bar => { … },
    else => |e| { … },
}

e will be of type @typeOf(err) but without the error.foo and error.bar variants

otherwise, im not sure
but remember you can always specify error sets yourself, that’s probably the easiest
and you could use comptime to generate a new error union based on another one so you could definitely play around with that
