type Incomparable ¶

type Incomparable [0]func()

Incomparable is a zero-width incomparable type. If added as the first field in a struct, it marks that struct as not comparable (can't do == or be a map key) and usually doesn't add any width to the struct (unless the struct has only small fields).

Be making a struct incomparable, you can prevent misuse (prevent people from using ==), but also you can shrink generated binaries, as the compiler can omit equality funcs from the binary.
