import NIOCoreThe core abstractions that make up SwiftNIO.
import NIOFoundationCompatstruct ByteBufferByteBuffer stores contiguously allocated raw bytes. It is a random and sequential accessible sequence of zero or more bytes (octets).
class JSONDecoderJSONDecoder facilitates the decoding of JSON into semantic Decodable types.
@frozen struct IntA signed integer value type.
protocol DecodableA type that can decode itself from an external representation.
init(data: Data) func getData(at index: Int, length: Int) -> Data? Return length bytes starting at index and return the result as Data. This will not change the reader index. The selected bytes must be readable or else nil will be returned.
func getData(at index: Int, length: Int, byteTransferStrategy: ByteTransferStrategy) -> Data? Return length bytes starting at index and return the result as Data. This will not change the reader index. The selected bytes must be readable or else nil will be returned.
func getJSONDecodable<T>(_ type: T.Type, decoder: JSONDecoder = JSONDecoder(), at index: Int, length: Int) throws -> T? where T : Decodable Attempts to decode the length bytes from index using the JSONDecoder decoder as T.
func getString(at index: Int, length: Int, encoding: String.Encoding) -> String? Get a String decoding length bytes starting at index with encoding. This will not change the reader index. The selected bytes must be readable or else nil will be returned.
func getUUIDBytes(at index: Int) -> UUID? Get a UUID from the 16 bytes starting at index. This will not change the reader index. If there are less than 16 bytes starting at index then nil will be returned.
mutating func readData(length: Int) -> Data? Read length bytes off this ByteBuffer, move the reader index forward by length bytes and return the result as Data.
mutating func readData(length: Int, byteTransferStrategy: ByteTransferStrategy) -> Data? Read length bytes off this ByteBuffer, move the reader index forward by length bytes and return the result as Data.
mutating func readString(length: Int, encoding: String.Encoding) -> String? Read a String decoding length bytes with encoding from the readerIndex, moving the readerIndex appropriately.
mutating func readUUIDBytes() -> UUID? Read a UUID from the first 16 bytes in the buffer. Advances the reader index.
