rustPointer cast example in Rust
Pointer casting in Rust is a way to convert a pointer of one type to a pointer of another type. This is done by using the as
keyword. For example, to convert a pointer of type *const i32
to a pointer of type *mut i32
, you can use the following code:
let ptr_const: *const i32 = &42;
let ptr_mut: *mut i32 = ptr_const as *mut i32;
Output example

Explanation
The as
keyword is used to cast the pointer ptr_const
of type *const i32
to a pointer of type *mut i32
. This is done by assigning the result of the cast to the variable ptr_mut
.
