rustHow to lowercase a string in Rust
You can lowercase a string in Rust using the to_lowercase()
method.
Example code:
let my_string = "HELLO WORLD";
let lowercase_string = my_string.to_lowercase();
println!("{}", lowercase_string);
Output
hello world
Explanation:
let my_string = "HELLO WORLD";
: This line declares a variablemy_string
and assigns it the value of the string"HELLO WORLD"
.let lowercase_string = my_string.to_lowercase();
: This line calls theto_lowercase()
method on themy_string
variable, which returns a new string with all characters in lowercase. This new string is then assigned to thelowercase_string
variable.println!("{}", lowercase_string);
: This line prints the value of thelowercase_string
variable to the console.
