Instance Method Detail

def close : Nil #
Description copied from class IO

Closes this IO.

IO defines this is a no-op method, but including types may override.


def closed? : Bool #

Returns true if this writer is closed.


def ctx : Zstd::Decompress::Context #

def dict(*args, **options) #

def dict(*args, **options, &) #

def dict=(arg) #

def read(slice : Bytes) #
Description copied from class IO

Reads at most slice.size bytes from this IO into slice. Returns the number of bytes read, which is 0 if and only if there is no more data to read (so checking for 0 is the way to detect end of file).

io = IO::Memory.new "hello"
slice = Bytes.new(4)
io.read(slice) # => 4
slice          # => Bytes[104, 101, 108, 108]
io.read(slice) # => 1
slice          # => Bytes[111, 101, 108, 108]
io.read(slice) # => 0

def sync_close=(sync_close) #

Whether to close the enclosed IO when closing this reader.


def sync_close? : Bool #

Whether to close the enclosed IO when closing this reader.


def write(slice : Bytes) : Nil #
Description copied from class IO

Writes the contents of slice into this IO.

io = IO::Memory.new
slice = Bytes.new(4) { |i| ('a'.ord + i).to_u8 }
io.write(slice)
io.to_s # => "abcd"
