Greetings everyone
I am trying to learn standard operator overloading and am practicing on my own sample code.
I read that due to Rust orphan rule I am not able to use operator overloading on Rust standard library types such as String.
For example, let us say I want to overload a Shift Left << operator (Shl Trait) on String.
This is impossible in Rust 1.54 because neither Shl Trait nor String is something introduced in my code.
I can understand why this rule exists, this is not my question.
BUT IF I wanted to be able to build something like this using << and >> operators on String data, is this possible?
Something like:
let mystr = "Hello Word!" << 6;
I expect mystr to have "World!" as the result of above pseudo-code, so by shifting the String to Left, I wiped off first 6 characters ("Hello ") and shrunk the result by same 6 characters after shift.
Is this possible with operator overloading using << and >> ?
Does it make sense?
I realize this is artificial, my aim is to learn and understand how to write idiomatic and ergonomic Rust using operator overloading.
Perhaps this is a stupid exercise that I have come up with?
Thank you very much!
