Struct zero_copy_pads::ErrorOnExcess [−][src]
pub struct ErrorOnExcess;
Forbid all excesses, panic once encounter one.
When value.width()
is not greater than total_width
,
add pads as usual:
use zero_copy_pads::{PaddedValue, AlignRight, ErrorOnExcess}; let padded_value = PaddedValue { handle_excess: ErrorOnExcess, value: "abcdef", pad_block: '-', total_width: 9, pad: AlignRight, }; assert_eq!(padded_value.to_string(), "---abcdef");
When value.width()
is greater than total_width
,
return an Err
of fmt::Error
:
use zero_copy_pads::{PaddedValue, AlignRight, ErrorOnExcess}; let padded_value = PaddedValue { handle_excess: ErrorOnExcess, value: "abcdefghijkl", pad_block: '-', total_width: 9, pad: AlignRight, }; let mut output = String::new(); std::fmt::write( &mut output, format_args!("{}", padded_value), ).unwrap_err();
