rustHow do I drop a variable in Rust?
Dropping a variable in Rust is done using the drop
function. This function takes a reference to a variable and deallocates the memory associated with it.
Example
let x = Box::new(5);
drop(x);
This code will deallocate the memory associated with the variable x
.
Code explanation
let x = Box::new(5);
: This line creates a new variablex
and allocates memory for it.drop(x);
: This line calls thedrop
function, which takes a reference to the variablex
and deallocates the memory associated with it.
