I understand Rust being type safe, but Im seeing syntax that Ive never seen in my life in Go which looks too messy

var test int < bruh what?

:=

func(u User) hi () { … } Where is the return type and why calling this fct doesnt require passing the u parameter but rather u.hi().

map := map[string] int {} < wtf

    To do quick and simple explanations:

    var test int = 0

    assign an int, var = let in rust land

    :=

    This is basically an inferred assignment e.g.

    a := "hello world"

    The compiler will know this is a string without me explicitly saying

    func (u User) hi() {}

    To return to rust land this is a function that implements User. In OOP land we would say that this function belongs to the user class. In Go, just like in rust we don’t say if a function returns void so this function is for User objects and doesn’t return anything:

    func (u User) hi(s string) string {}

    If it took in a string and returned a string it would look like this.

    map[string] int {}

    I will give you that this syntax is a bit odd but this is just a hashmap/dictionary where the key is a string and the value is an int
