# DataProtocol

A protocol that provides consistent data access to the bytes underlying contiguous and noncontiguous data buffers.

```
protocol DataProtocol : RandomAccessCollection where Self.Element == UInt8, Self.SubSequence : DataProtocol
```

## Topics

### Accessing Backing Storage

[`regions`](/documentation/Foundation/DataProtocol/regions-swift.property)

A collection of buffers that make up the whole of the type conforming to a data protocol.

[`Regions`](/documentation/Foundation/DataProtocol/Regions-swift.associatedtype)

A type that represents a collection of contiguous parts that make up the type conforming to a data protocol.

### Copying Underlying Bytes

[`copyBytes(to:)`](/documentation/Foundation/DataProtocol/copyBytes(to:)-52wps)

Copies the bytes of data from the type into a typed memory buffer.

[`copyBytes(to:)`](/documentation/Foundation/DataProtocol/copyBytes(to:)-3mk27)

Copies the bytes of data from the type into a raw memory buffer.

[`copyBytes(to:count:)`](/documentation/Foundation/DataProtocol/copyBytes(to:count:)-6krsm)

Copies the provided number of bytes from the start of the type into  a typed memory buffer.

[`copyBytes(to:count:)`](/documentation/Foundation/DataProtocol/copyBytes(to:count:)-29t5)

Copies the provided number of bytes from the start of the type into a raw memory buffer.

[`copyBytes(to:from:)`](/documentation/Foundation/DataProtocol/copyBytes(to:from:)-1ol47)

Copies a range of the bytes from the type into a typed memory buffer.

[`copyBytes(to:from:)`](/documentation/Foundation/DataProtocol/copyBytes(to:from:)-1y839)

Copies a range of the bytes from the type into a raw memory buffer.

### Searching Within Data

[`firstRange(of:)`](/documentation/Foundation/DataProtocol/firstRange(of:))

Returns the first found range of the type’s data buffer.

[`firstRange(of:in:)`](/documentation/Foundation/DataProtocol/firstRange(of:in:))

Returns the first found range of the type’s data buffer.

[`lastRange(of:)`](/documentation/Foundation/DataProtocol/lastRange(of:))

Returns the last found range of the type’s data buffer.

[`lastRange(of:in:)`](/documentation/Foundation/DataProtocol/lastRange(of:in:))

Returns the last found range of the type’s data buffer.
