Struct zero_copy_pads::ExcessHandlingFunction [−][src]
pub struct ExcessHandlingFunction<Value, PadBlock = char>(pub fn(_: Excess<'_, Value, PadBlock>, _: &mut Formatter<'_>) -> Result<(), Error>)
where
Value: Width,
PadBlock: Display;
Turn a function (without closure) into a ExcessHandler
.
Example: Truncate to make it fit
use zero_copy_pads::{ExcessHandlingFunction, Excess, PaddedValue, AlignRight}; use std::fmt::{Formatter, Result}; let truncate = ExcessHandlingFunction::<&str>(|excess, formatter| { let mut value = excess.value.to_string(); value.truncate(excess.total_width); write!(formatter, "{}", value) }); let padded_value = PaddedValue { handle_excess: truncate, value: "abcdefghi", total_width: 4, pad_block: ' ', pad: AlignRight, }; assert_eq!(padded_value.to_string(), "abcd");
