`anytype` for Writer interfaces

[hybrid oyster]

Is there an anytype like thing, but for Writer interfaces?
Basically a struct field will take any type of Writer, but I'm having trouble expressing that to Zig..

not sure what you mean but there's std.io.AnyWriter if you want a type-erased writer, like std.io.AnyReader

or potentially std.io.GenericWriter if you just want to give it a function and an error set

[hybrid oyster]

writer: std.io.AnyWriter,

pub fn init(writer: anytype) Self {
    return .{
        .writer = writer,
    };
}

im trying to make it work for any type of writer basically

[coral tide]

writer.any()

[hybrid oyster]

oh wow

that worked
