Trait std::slice::SliceConcatExt
pub trait SliceConcatExt<T> where T: ?Sized, {

fn concat(&self) -> Self::Output;
fn join(&self, sep: &T) -> Self::Output;
fn connect(&self, sep: &T) -> Self::Output;
}
???? This is a nightly-only experimental API. (slice_concat_ext #27747)trait should not have to exist
An extension trait for concatenating slices
Associated Types
type Output
???? This is a nightly-only experimental API. (slice_concat_ext #27747)trait should not have to exist
The resulting type after concatenation
Required Methods
fn concat(&self) -> Self::Output1.0.0
Flattens a slice of T into a single value Self::Output.
Examples
assert_eq!(["hello", "world"].concat(), "helloworld");
fn join(&self, sep: &T) -> Self::Output1.3.0
Flattens a slice of T into a single value Self::Output, placing a given separator between each.
Examples
assert_eq!(["hello", "world"].join(" "), "hello world"); fn connect(&self, sep: &T) -> Self::Output1.0.0
Deprecated since 1.3.0: renamed to join
