[−][src]Struct sub_strs::CainStr
Case-insensitive string
Notes
- This struct is intended for sorting in lists, or to be used in sets, so it generates a lower-case form of source string and stores it
inside. That might look like a waste of memory, but it helps with performance. For example when you call
Vec::sort()
or when you insert it into aHashSet
, it doesn't have to generate any string again and again... - Implementations of
From<&'a str>
,From<&'a String>
andFrom<String>
either borrow or take the source string and store it inside. - Implementation of
FromStr
will clone the source strings.
Examples
use std::collections::HashSet; use std::convert::TryFrom; use sub_strs::CainStr; let wild_data: HashSet<_> = vec!["swift", "C++", "rust", "SWIFT"].into_iter().collect(); assert_eq!(wild_data.len(), 4); let data: HashSet<_> = wild_data.into_iter().map(|s| CainStr::from(s)).collect(); assert_eq!(data.len(), 3); let mut data: Vec<_> = data.into_iter().collect(); data.sort(); let data: Vec<_> = data.iter().map(|cs| cs.as_ref()).collect(); assert_eq!(&data[..2], &["C++", "rust"]); assert!(data[2].eq_ignore_ascii_case("swift"));
