rustHow do I define a variable in Rust?
A variable in Rust is a way to store a value in memory. Variables are declared using the let
keyword, followed by the variable name and a type annotation.
let x: i32 = 5;
The code above declares a variable x
of type i32
and assigns it the value 5
.
let
: keyword used to declare a variablex
: name of the variable: i32
: type annotation= 5
: value assigned to the variable
