rustHow to get pointer to variable in Rust
In Rust, you can get a pointer to a variable by using the &
operator. For example, if you have a variable x
of type i32
, you can get a pointer to it by writing let x_ptr = &x
. The &
operator returns a pointer to the variable, which can then be used to access the value of the variable. Additionally, you can use the *
operator to dereference a pointer and access the value of the variable it points to. For example, if x_ptr
is a pointer to x
, you can access the value of x
by writing *x_ptr
.
