fix: rust is functional

[spotlesscoder]

"method" is a term that usually refers to functions provided by a class in OOP as Rust is functional, rather use the term function

[ghost]

In my research, the group of functions wrapping_* are indeed methods.
A method is a function associated with a type: so associated that the first parameter is 'self'.
Note that in C++, structs can also have methods.

Thanks for the suggestion, but actually Rust is not strictly functional, "methods" are not strictly limited to object-oriented languages (a method is a function which are associated with a specific data structure, with or without reference to a specific instance), and Rust has both functions and methods!

[spotlesscoder]

OK - but what's the difference between a method and a function in Rust?

[chriskrycho]

A method is a function which is attached to a data type (a struct or an enum). It appears in an impl block for that type. So all methods are functions, but not all functions are methods!

Thanks for the clarification
Today I learned :)
