Rust Comments

In Rust, comments are used to add explanatory notes or documentation within the code. Comments are ignored by the compiler and do not affect the execution of the program. Rust supports two types of comments: line comments and block comments.

Line comments start with two forward slashes (//) and continue until the end of the line. They are typically used for short comments or explanations on a single line.

// This is a line comment
let x = 5; // Assigning a value to x

Block comments start with a forward slash followed by an asterisk (/) and end with an asterisk followed by a forward slash (/). They can span multiple lines and are often used for longer comments or explanations.

/* This is a block comment
   It can span multiple lines
   and is useful for longer comments */
let y = 10; / Assigning a value to y /

It's important to note that comments are not executed by the program and are purely for human understanding and documentation purposes.
