Methods

Ensure(int, bool)

Ensures that count bytes are available in the buffer, and if not, reads from the socket until enough is available.

public Task Ensure(int count, bool async)

Parameters

async bool

Returns

Task

GetStream(int, bool)

public Stream GetStream(int len, bool canSeek)

Parameters

len int

canSeek bool

Returns

Stream

ReadByte()

public byte ReadByte()

Returns

byte

ReadBytes(byte[], int, int)

public void ReadBytes(byte[] output, int outputOffset, int len)

Parameters

output byte[]

outputOffset int

len int

ReadBytes(byte[], int, int, bool)

public ValueTask<int> ReadBytes(byte[] output, int outputOffset, int len, bool async)

Parameters

output byte[]

outputOffset int

len int

Returns

ValueTask<int>

ReadBytes(Span<byte>)

public void ReadBytes(Span<byte> output)

Parameters
