rustHow can I pad a Rust string to the left?
You can pad a Rust string to the left using the pad_start
method. This method takes two parameters, the first being the desired length of the string and the second being the character to pad the string with.
For example:
let s = "Hello".to_string();
let padded = s.pad_start(10, ' ');
println!("{}", padded);
Output example
Hello
The code above pads the string Hello
with spaces until it reaches a length of 10 characters.
The parts of the code are:
let s = "Hello".to_string();
: This creates a string from the literalHello
.let padded = s.pad_start(10, ' ');
: This calls thepad_start
method on the strings
with the parameters10
and' '
(a single space character).println!("{}", padded);
: This prints the padded string to the console.
