`module Reader`

General operations for interacting with a request or response body.

Definitions

`def each(&block)`

Read chunks from the body.

Signature

yields　{|chunk| ...}: chunks from the body.

Implementation

def each(&block)
	if @body
		@body.each(&block)
		@body = nil
	end
end

`def read`

Reads the entire request/response body.

Signature

returns　String: the entire body as a string.

Implementation

def read
	if @body
		buffer = @body.join
		@body = nil
		
		return buffer
	end
end

`def finish`

Gracefully finish reading the body. This will buffer the remainder of the body.

Signature

returns　Buffered: buffers the entire body.

Implementation

def finish
	if @body
		body = @body.finish
		@body = nil
		
		return body
	end
end

`def discard`

Discard the body as efficiently as possible.

Implementation

def discard
	if body = @body
		@body = nil
		body.discard
	end
end

`def buffered!`

Buffer the entire request/response body.

Signature

returns　Reader: itself.

Implementation

def buffered!
	if @body
		@body = @body.finish
	end
	
	return self
end

`def save(path, mode = ::File::WRONLY|::File::CREAT|::File::TRUNC, **options)`

Write the body of the response to the given file path.

Implementation

def save(path, mode = ::File::WRONLY|::File::CREAT|::File::TRUNC, **options)
	if @body
		::File.open(path, mode, **options) do |file|
			self.each do |chunk|
				file.write(chunk)
			end
		end
	end
end

`def close(error = nil)`

Close the connection as quickly as possible. Discards body. May close the underlying connection if necessary to terminate the stream.

Implementation

def close(error = nil)
	if @body
		@body.close(error)
		@body = nil
	end
end

`def body?`

Whether there is a body?

Implementation

def body?
	@body and !@body.empty?
end
