Rust–: Rust without the borrow checker

Summary

Rust--: Rust without the borrow checker A modified Rust compiler with the borrow checker disabled. This allows code that would normally violate Rust's borrowing rules to compile and run successfully.

Examples: Before vs After Example 1: Move Then Use Normal Rust: fn main ( ) { let a = String :: from ( "hello" ) ; let b = a ; println ! ( "{a}" ) ; } Error in normal Rust: error[E0382]: borrow of moved value: `a` --> test.rs:4:16 | 2 | let a = String::from("hello"); | - move occurs because `a` has type `String`, which does not implement the `Copy` trait 3 | let b = a; | - value moved here 4 | println!("{a}"); | ^ value borrowed here after move Rust--: fn main ( ) { let a = String :: from ( "hello" ) ; let b = a ; println ! ( "{a}" ) ; // Works! Prints: hello } Example 2: Multiple Mutable References Normal Rust: fn main ( ) { let mut y = 5 ; let ref1 = & mut y ; let ref2 = & mut y ; * ref1 = 10 ; * ref2 = 20 ; } Error in normal Rust: error[E0499]: cannot borrow `y` as mutable more than once at a time --> test.rs:4:16 | 3 | let ref1 = &mut y; | ------ first mutable borrow occurs here 4 | let ref2 = &mut y; | ^^^^^^ second mutable borrow occurs here 5 | *ref1 = 10; | ---------- first borrow later used here Rust--: fn main ( ) { let mut y = 5 ; let ref1 = & mut y ; let ref2 = & mut y ; // Works! * ref1 = 10 ; * ref2 = 20 ; println ! ( "{}" , y ) ; // Prints: 20 } Example 3: Mutable Borrow Then Move Normal Rust: fn main ( ) { let mut x = vec ! [ 1 , 2 , 3 ] ; let borrowed = & mut x ; println ! ( "{:?}" , x ) ; // ERROR: cannot use `x` while mutable borrow exists } Rust--: fn main ( ) { let mut x = vec ! [ 1 , 2 , 3 ] ; let borrowed = & mut x ; println ! ( "{:?}" , x ) ; // Works! Prints: [1, 2, 3] } Example 4: Use After Move in Loop Normal Ru...
