Function fmty::concat

pub fn concat<I>(iter: I) -> Concat<I::IntoIter>where
    I: IntoIterator,
    I::IntoIter: Clone,

Concatenates Iterator items.

This is a non-allocating alternative to [T]::concat().

If Clone for the Iterator is too expensive, consider using concat_once().

Although this can be used to conditionally write an Option (because it implements IntoIterator), consider using cond_option() for this instead.

Examples

let value = fmty::concat(["hola", "mundo"]);
assert_eq!(value.to_string(), "holamundo");
