Trait compact_str::CompactStringExt
source · pub trait CompactStringExt {
// Required methods
fn concat_compact(&self) -> CompactString;
fn join_compact<S: AsRef<str>>(&self, seperator: S) -> CompactString;
}
Expand description
A trait that provides convience methods for creating a CompactString
from a collection of
items. It is implemented for all types that can be converted into an iterator, and that iterator
yields types that can be converted into a str
.
i.e. C: IntoIterator<Item = AsRef<str>>
.
Concatenate and Join
Two methods that this trait provides are concat_compact(...)
and join_compact(...)
use compact_str::CompactStringExt;
let words = vec!["☀️", "🌕", "🌑", "☀️"];
// directly concatenate all the words together
let concat = words.concat_compact();
assert_eq!(concat, "☀️🌕🌑☀️");
// join the words, with a seperator
let join = words.join_compact(" ➡️ ");
assert_eq!(join, "☀️ ➡️ 🌕 ➡️ 🌑 ➡️ ☀️");
Required Methods§
sourcefn concat_compact(&self) -> CompactString
fn concat_compact(&self) -> CompactString
Concatenates all the items of a collection into a CompactString
Example
use compact_str::CompactStringExt;
let items = ["hello", " ", "world", "!"];
let compact = items.concat_compact();
assert_eq!(compact, "hello world!");
sourcefn join_compact<S: AsRef<str>>(&self, seperator: S) -> CompactString
fn join_compact<S: AsRef<str>>(&self, seperator: S) -> CompactString
Joins all the items of a collection, placing a seperator between them, forming a
CompactString
Example
use compact_str::CompactStringExt;
let fruits = vec!["apples", "oranges", "bananas"];
let compact = fruits.join_compact(", ");
assert_eq!(compact, "apples, oranges, bananas");
