Control Flow in Rust

Control flow in Rust gives you the ability to execute code based on a condition. We have a few ways to control the flow of our program in Rust.

If Expressions

The most basic form of control flow is the if expression along with the else and else if expressions.

Loops

Loops are a way to execute code repeatedly until a certain condition is met. Rust has three kinds of loops: loop, while, and for.

Pattern matching

Rust provides a way to do a more complex form of control flow using pattern matching, you can use match to compare a value against a series of patterns and then execute code based on which pattern matches, or you can use the if let expression to match a single pattern.
