RUST Switch case
The switch statement allows us to execute one code block among many alternatives.You can do the same thing with the if...else..if ladder. However, the syntax of the switch statement is much easier to read and write.
Switch statements express conditionals across many branches.
In RUST, Switch case are written using match function.
A match statement allows a variable to be tested against a list of values.
Example of Switch case in RUST using match
fn main(){
let state_code="NY";
let state = match state_code {
"NY" => {
println!("Found match for NY");
"New York"},
"MI" => "Michigan",
"FL" => "Florida",
"GA" => "Georgia",
_ => "Unknown"
};
println!("State name is {}",state);
}Conclusion
