Function datafusion_functions::unicode::lpad::lpad

pub fn lpad<T: OffsetSizeTrait>(args: &[ArrayRef]) -> Result<ArrayRef>

Extends the string to length ‘length’ by prepending the characters fill (a space by default). If the string is already longer than length then it is truncated (on the right). lpad(‘hi’, 5, ‘xy’) = ‘xyxhi’
