Expand description

A trait for converting collections into Join instances.

This trait is implemented for all referentially iterable types; that is, for all types for which &T: IntoIterator. See join_with for an example of its usage.

Required Associated Types

Required Methods

Combine this object with a separator to create a new Join instance. Note that the separator does not have to share the same type as the iterator’s values.

Examples
use joinery::Joinable;

let parts = vec!["this", "is", "a", "sentence"];
let join = parts.join_with(' ');
assert_eq!(join.to_string(), "this is a sentence");

Provided Methods

Join this object with an empty separator. When rendered with Display, the underlying elements will be directly concatenated. Note that the separator, while empty, is still present, and will show up if you iterate this instance.

Examples
use joinery::Joinable;

let parts = vec!['a', 'b', 'c', 'd', 'e'];
let join = parts.join_concat();
assert_eq!(join.to_string(), "abcde");
