rustHow to borrow as static in Rust
Static borrowing in Rust is a way to borrow a value without taking ownership of it. This allows the value to be used without having to move it.
let mut x = 5;
{
let y = &x; // y is a reference to x
println!("{}", y);
}
x = 6;
Output example
5
The code above shows an example of static borrowing. The variable x
is declared as mutable and assigned the value 5
. A reference to x
is then created and assigned to y
. The reference y
is then used to print the value of x
. Finally, the value of x
is changed to 6
.
The parts of the code are:
let mut x = 5;
: This declares a mutable variablex
and assigns it the value5
.let y = &x;
: This creates a reference tox
and assigns it toy
.println!("{}", y);
: This prints the value ofx
using the referencey
.x = 6;
: This changes the value ofx
to6
.
