rustHow do I borrow a variable in Rust?
In Rust, variables can be borrowed using the &
operator. This operator creates a reference to the variable, allowing it to be used without taking ownership of it.
For example:
let x = 5;
let y = &x;
This code creates a reference y
to the variable x
, which has the value 5
.
The parts of this code are:
let x = 5;
: This declares a variablex
with the value5
.let y = &x;
: This creates a referencey
to the variablex
.
For more information, see the Rust Reference.
