The resulting type after concatenation

Required Methods

fn concat(&self) -> Self::Output

Flattens a slice of T into a single value Self::Output.

Examples

fn main() { assert_eq!(["hello", "world"].concat(), "helloworld"); }

assert_eq!(["hello", "world"].concat(), "helloworld");

fn join(&self, sep: &T) -> Self::Output

Flattens a slice of T into a single value Self::Output, placing a given separator between each.

Examples

fn main() { assert_eq!(["hello", "world"].join(" "), "hello world"); }

assert_eq!(["hello", "world"].join(" "), "hello world");

fn connect(&self, sep: &T) -> Self::Output

Deprecated since 1.3.0

: renamed to join
