Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x
returned by block
is decomposed if either of the following conditions is true:
x
responds to both each and force, which means that x
is a lazy enumerator.
x
is an array or responds to to_ary.
Otherwise, x
is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force #=> [{:a=>1}, {:b=>2}]
Like Enumerable#take_while
, but chains operation to be lazy-evaluated.
Like Enumerable#map
, but chains operation to be lazy-evaluated.
(1..Float::INFINITY).lazy.map {|i| i**2 } #=> #<Enumerator::Lazy: #<Enumerator::Lazy: 1..Infinity>:map> (1..Float::INFINITY).lazy.map {|i| i**2 }.first(3) #=> [1, 4, 9]
Like Enumerable#take
, but chains operation to be lazy-evaluated.

Sets the cipher’s additional authenticated data. This field must be set when using AEAD cipher modes such as GCM or CCM. If no associated data shall be used, this method must still be called with a value of “”. The contents of this field should be non-sensitive data which will be added to the ciphertext to generate the authentication tag which validates the contents of the ciphertext.
The AAD must be set prior to encryption or decryption. In encryption mode, it must be set after calling Cipher#encrypt
and setting Cipher#key=
and Cipher#iv=
. When decrypting, the authenticated data must be set after key, iv and especially after the authentication tag has been set. I.e. set it only after calling Cipher#decrypt
, Cipher#key=
, Cipher#iv=
and Cipher#auth_tag=
first.
