hash :: (key: rawptr) -> u32

    where hash.Hashable(First_Type), hash.Hashable(Second_Type)
hash :: (key: i8) -> u32

hash :: (key: $T) -> u32

hash :: macro (key: $T) -> #auto
    where HasHashMethod(T)

This overloaded procedure defines how to hash something. It is used throughout the standard library to hash values. There are many overloads to it in the standard library, and more can be added using #overload.

Alternatively, a hash method can be defined for a structure or distinct type.

Person :: struct {
    hash :: (p: Person) -> u32 {
        return // ...
    }
}
