rustWhat type of variable declaration is used in Rust?
Rust uses a type of variable declaration called a let statement. This statement is used to declare a variable and assign it a value. For example, the following code declares a variable x and assigns it the value 5:
let x = 5;The code consists of three parts:
- The keyword
let, which is used to declare a variable. - The variable name
x, which is used to refer to the variable. - The value
5, which is assigned to the variable.
Variables declared with let are immutable, meaning their value cannot be changed once they are declared.
For more information about variable declarations in Rust, see the Rust Book.
