Struct zero_copy_pads::ErrorOnExcess[−][src]

pub struct ErrorOnExcess;

Forbid all excesses, raise fmt::Error 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();
