Trait collections::slice::SliceConcatExtUnstable [-] [+] [src]

pub trait SliceConcatExt<T: ?Sized, U> {
    fn concat(&self) -> U;
    fn connect(&self, sep: &T) -> U;
}

An extension trait for concatenating slices

Required Methods

fn concat(&self) -> U

Flattens a slice of T into a single value U.

Examples

fn main() { let v = vec!["hello", "world"]; let s: String = v.concat(); println!("{}", s); // prints "helloworld" }
let v = vec!["hello", "world"];

let s: String = v.concat();

println!("{}", s); // prints "helloworld"

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

Flattens a slice of T into a single value U, placing a given separator between each.

Examples

fn main() { let v = vec!["hello", "world"]; let s: String = v.connect(" "); println!("{}", s); // prints "hello world" }
let v = vec!["hello", "world"];

let s: String = v.connect(" ");

println!("{}", s); // prints "hello world"
