Crate stringslice
source ·Expand description
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);
