Crate stringslice 

A collection of methods to slice strings based on character indices rather than bytes.

This crate implements the StringSlice trait for &str, containing the slice, try_slice, substring, and try_substring methods.

Examples

The slice method can be used to slice a &str.

use stringslice::StringSlice;

assert_eq!("Ùníc😎de".slice(4..5), "😎");
assert_eq!("世界こんにちは".slice(2..), "こんにちは");

The substring method is provided for convenience and accepts separate parameters for the start and end of the slice.

use stringslice::StringSlice;

assert_eq!("Γεια σου κόσμε".substring(9, 14), "κόσμε");

There are also equivalent try_slice and try_substring methods which return None for invalid input.

use stringslice::StringSlice;

assert_eq!("string".try_slice(4..2), None);
