Places a given value in between each element of the asynchronous sequence.
let numbers = [1, 2, 3].async.interspersed(with: 0)
for await number in numbers {
print(number)
}
// prints 1 0 2 0 3
let empty = [].async.interspersed(with: 0)
// await Array(empty) == []interspersed(with:) takes a separator value and inserts it in between every
element in the asynchronous sequence.
A new method is added to AsyncSequence:
extension AsyncSequence {
func interspersed(with separator: Element) -> AsyncInterspersedSequence<Self>
}The new AsyncInterspersedSequence type represents the asynchronous sequence
when the separator is inserted between each element.
When the base asynchronous sequence can throw on iteration, AsyncInterspersedSequence
will throw on iteration. When the base does not throw, the iteration of
AsyncInterspersedSequence does not throw either.
AsyncInterspersedSequence is conditionally Sendable when the base asynchronous
sequence is Sendable and the element is also Sendable.
This method’s and type’s name match the term of art used in other languages and libraries.
This method is a direct analog to the synchronous version defined in the Swift Algorithms package.
Haskell: Has an intersperse function which takes an element
and a list and 'intersperses' that element between the elements of the list.
Rust: Has a function called intersperse to insert a particular
value between each element.
