String.padStart

Method

String.padStart(width: u32, fill: char) -> String

Pads the beginning of this string to a minimum Unicode-scalar length.

The original string is returned unchanged when it already contains at least width Unicode scalar values. Otherwise fill is repeated before it. This measures scalar values, not UTF-8 bytes or terminal columns.

Parameters

• width: The minimum number of Unicode scalar values in the result.
• fill: The character repeated before the original string.

Effects: allocates

Runtime behavior: available everywhere; synchronous

Examples

Zero-pad a numeric identifier

let identifier = "7".padStart(3, '0')
