Trait collections::slice::SliceConcatExt
[−]
[src]
pub trait SliceConcatExt<T: ?Sized> { type Output; fn concat(&self) -> Self::Output; fn join(&self, sep: &T) -> Self::Output; fn connect(&self, sep: &T) -> Self::Output; }
An extension trait for concatenating slices
Associated Types
type Output
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
