Struct flatcontainer::impls::string::StringRegion
source · pub struct StringRegion<R = CopyRegion<u8>>{ /* private fields */ }
Expand description
A region to store strings and read &str
.
Delegates to a region R
to store u8
slices. By default, it uses a CopyRegion
, but a
different region can be provided, as long as it absorbs and reads items as &[u8]
.
§Examples
We fill some data into a string region and use extract it later.
use flatcontainer::{Containerized, CopyOnto, CopyRegion, Region, StringRegion};
let mut r = <StringRegion>::default();
let panagram_en = "The quick fox jumps over the lazy dog";
let panagram_de = "Zwölf Boxkämpfer jagen Viktor quer über den großen Sylter Deich";
let en_index = panagram_en.copy_onto(&mut r);
let de_index = panagram_de.copy_onto(&mut r);
assert_eq!(panagram_de, r.index(de_index));
assert_eq!(panagram_en, r.index(en_index));
