[−][src]Struct core_extensions::slices::SliceBias

pub struct SliceBias {
    pub start: BiasDirection,
    pub end: BiasDirection,
}

What directions SliceExt::slice_lossy[_mut] is biased towards.

For str this has the effect of going in those directions if the start/end bound is between char boundaries.

For [T] this has no effect and it is recommended to use () as a parameter instead.

Example

use core_extensions::SliceExt;
use core_extensions::slices::SliceBias;

let word="niño";

assert_eq!(
    word.char_indices().collect::<Vec<_>>(),
    &[(0,'n'),(1,'i'),(2,'ñ'),(4,'o')]
