struct HexDecodingErrorAn error that is thrown when an invalid hex encoded string was attempted to be written to a ByteBuffer.
struct HexDecodingErrorimport NIOCoreThe core abstractions that make up SwiftNIO.
struct ByteBufferByteBuffer stores contiguously allocated raw bytes. It is a random and sequential accessible sequence of zero or more bytes (octets).
init() Return an empty ByteBuffer allocated with ByteBufferAllocator().
init(_ view: ByteBufferView) Create a ByteBuffer from the given ByteBufferViews range.
init(buffer: ByteBuffer) Create a fresh ByteBuffer containing the readable bytes of buffer.
init<Bytes>(bytes: Bytes) where Bytes : Sequence, Bytes.Element == UInt8 Create a fresh ByteBuffer containing the bytes.
init(dispatchData: DispatchData) Create a fresh ByteBuffer containing the bytes contained in the given DispatchData.
init(from decoder: Decoder) throws Creates a ByteByffer by decoding from a Base64 encoded single value container.
init<I>(integer: I, endianness: Endianness = .big, as: I.Type = I.self) where I : FixedWidthInteger Create a fresh ByteBuffer containing the bytes of the byte representation in the given endianness of integer.
init(plainHexEncodedBytes string: String) throws Create a fresh ByteBuffer containing the bytes decoded from the string representation of plainHexEncodedBytes.
init(repeating byte: UInt8, count: Int) Create a fresh ByteBuffer containing count repetitions of byte.
init(staticString string: StaticString) Create a fresh ByteBuffer containing the bytes of the string encoded as UTF-8.
init(string: String) Create a fresh ByteBuffer containing the bytes of the string encoded as UTF-8.
init(substring string: Substring) Create a fresh ByteBuffer containing the bytes of the string encoded as UTF-8.
var capacity: Int { get }The current capacity of the storage of this ByteBuffer, this is not constant and does not signify the number of bytes that have been written to this ByteBuffer.
var debugDescription: String { get }var description: String { get }A String describing this ByteBuffer including length and the bytes it contains (partially).
var readableBytes: Int { get }The number of bytes readable (readableBytes = writerIndex - readerIndex).
var readableBytesView: ByteBufferView { get }A view into the readable bytes of the ByteBuffer.
var readerIndex: Int { get }The reader index or the number of bytes previously read from this ByteBuffer. readerIndex is 0 for a newly allocated ByteBuffer.
var storageCapacity: Int { get }The current capacity of the underlying storage of this ByteBuffer. A COW slice of the buffer (e.g. readSlice(length: x)) will posses the same storageCapacity as the original buffer until new data is written.
var writableBytes: Int { get }The number of bytes writable until ByteBuffer will need to grow its underlying storage which will likely trigger a copy of the bytes.
var writerIndex: Int { get }The write index or the number of bytes previously written to this ByteBuffer. writerIndex is 0 for a newly allocated ByteBuffer.
static func == (lhs: ByteBuffer, rhs: ByteBuffer) -> Bool Compare two ByteBuffer values. Two ByteBuffer values are considered equal if the readable bytes are equal.
mutating func clear() Set both reader index and writer index to 0. This will reset the state of this ByteBuffer to the state of a freshly allocated one, if possible without allocations. This is the cheapest way to recycle a ByteBuffer for a new use-case.
mutating func clear(minimumCapacity: Int) Set both reader index and writer index to 0. This will reset the state of this ByteBuffer to the state of a freshly allocated one, if possible without allocations. This is the cheapest way to recycle a ByteBuffer for a new use-case.

@discardableResult mutating func writePlainHexEncodedBytes(_ plainHexEncodedBytes: String) throws -> Int Write ASCII hexadecimal string into this ByteBuffer as raw bytes, decoding the hexadecimal & moving the writer index forward appropriately. This method will throw if the string input is not of the “plain” hex encoded format.
@discardableResult mutating func writeRepeatingByte(_ byte: UInt8, count: Int) -> Int Writes byte count times. Moves the writer index forward by the number of bytes written.
@discardableResult mutating func writeStaticString(_ string: StaticString) -> Int Write the static string into this ByteBuffer using UTF-8 encoding, moving the writer index forward appropriately.
@discardableResult mutating func writeString(_ string: String) -> Int Write string into this ByteBuffer using UTF-8 encoding, moving the writer index forward appropriately.
@discardableResult mutating func writeSubstring(_ substring: Substring) -> Int Write substring into this ByteBuffer using UTF-8 encoding, moving the writer index forward appropriately.
@discardableResult mutating func writeWithUnsafeMutableBytes(minimumWritableBytes: Int, _ body: (UnsafeMutableRawBufferPointer) throws -> Int) rethrows -> Int This vends a pointer of the ByteBuffer at the writerIndex after ensuring that the buffer has at least minimumWritableBytes of writable bytes available.
struct CopyBytesErrorErrors thrown when calling copyBytes.
struct HexDumpFormatDescribes a ByteBuffer hexDump format. Can be either xxd output compatible, or hexdump compatible.
struct LengthPrefixErrorstruct QUICBinaryEncodingStrategyA NIOBinaryIntegerEncodingStrategy which encodes bytes as defined in RFC 9000 § 16
struct ReadUTF8ValidationErrorErrors thrown when calling readUTF8ValidatedString or getUTF8ValidatedString.
typealias _Capacity = UInt32typealias _Index = UInt32mutating func clear(minimumCapacity: UInt32) Set both reader index and writer index to 0. This will reset the state of this ByteBuffer to the state of a freshly allocated one, if possible without allocations. This is the cheapest way to recycle a ByteBuffer for a new use-case.
@discardableResult mutating func set(buffer: ByteBuffer, at index: Int) -> Int Copy buffer’s readable bytes into this ByteBuffer starting at index. Does not move any of the reader or writer indices.
@discardableResult mutating func writeWithUnsafeMutableBytes(_ body: (UnsafeMutableRawBufferPointer) throws -> Int) rethrows -> Int protocol EquatableA type that can be compared for value equality.
protocol Error : SendableA type representing an error value that can be thrown.
protocol Sendablestatic let invalidCharacter: ByteBuffer.HexDecodingErrorstatic let invalidHexLength: ByteBuffer.HexDecodingErrorstatic func != (lhs: Self, rhs: Self) -> Bool Returns a Boolean value indicating whether two values are not equal.
