# SE0270_RangeSet
**SE0270_RangeSet** is a standalone library that implements the Swift Evolution proposal
[SE-0270: Add Collection Operations on Noncontiguous Elements][proposal].
You can use this package independently,
or as part of the [standard library preview package][stdlib-preview].
## Functionality
**SE0270_RangeSet** provides operations on noncontiguous subranges of collections,
such as `subranges(where:)` and `moveSubranges(_:to:)`,
as well as the supporting `RangeSet` type.
```swift
import SE0270_RangeSet
var numbers = [10, 12, -5, 14, -3, -9, 15]
let negatives = numbers.subranges(where: { $0 < 0 })
// numbers[negatives].count == 3
numbers.moveSubranges(negatives, to: 0)
// numbers == [-5, -3, -9, 10, 12, 14, 15]
```
## Usage
You can add this library as a dependency to any Swift package.
Add this line to the `dependencies` parameter in your `Package.swift` file:
```swift
.package(
url: "https://github.com/apple/swift-se0270-range-set",
from: "1.0.0"),
```
Next, add the module as a dependency for your targets that will use the library:
```swift
.product(name: "SE0270_RangeSet", package: "swift-se0270-range-set"),
```
You can now use `import SE0270_RangeSet` to make the library available in any Swift file.
