Pushes character c back onto the stream such that a subsequent buffered character read will return it.

Unlike IO#getc multiple bytes may be pushed back onto the stream.

Has no effect on unbuffered reads (such as sysread).

Return true if the PRNG has been seeded with enough data, false otherwise.

Generate a Checkbox Input element as a string.

The attributes of the element can be specified as three arguments, name, value, and checked. checked is a boolean value; if true, the CHECKED attribute will be included in the element.

Alternatively, the attributes can be specified as a hash.

checkbox("name")
  # = checkbox("NAME" => "name")

checkbox("name", "value")
  # = checkbox("NAME" => "name", "VALUE" => "value")

checkbox("name", "value", true)
  # = checkbox("NAME" => "name", "VALUE" => "value", "CHECKED" => true)

Returns true if field 'Transfer-Encoding' exists and has value 'chunked', false otherwise; see Transfer-Encoding response header:

res = Net::HTTP.get_response(hostname, '/todos/1')
res['Transfer-Encoding'] # => "chunked"
res.chunked?             # => true

returns a charset parameter in Content-Type field. It is downcased for canonicalization.

If charset parameter is not given but a block is given, the block is called and its result is returned. It can be used to guess charset.

If charset parameter and block is not given, nil is returned except text type. In that case, “utf-8” is returned as defined by RFC6838 4.2.1
