        # Zlib::Inflate.inflate

(from ruby core)
### Implementation from Inflate
---
    Zlib.inflate(string)
    Zlib::Inflate.inflate(string)

---

Decompresses `string`. Raises a Zlib::NeedDict exception if a preset
dictionary is needed for decompression.

This method is almost equivalent to the following code:

    def inflate(string)
      zstream = Zlib::Inflate.new
      buf = zstream.inflate(string)
      zstream.finish
      zstream.close
      buf
    end

(from ruby core)
### Implementation from Inflate
---
    inflate(deflate_string, buffer: nil)                 -> String
    inflate(deflate_string, buffer: nil) { |chunk| ... } -> nil

---

Inputs `deflate_string` into the inflate stream and returns the output
from the stream.  Calling this method, both the input and the output
buffer of the stream are flushed.  If string is `nil`, this method
finishes the stream, just like Zlib::ZStream#finish.

If a block is given consecutive inflated chunks from the
`deflate_string` are yielded to the block and `nil` is returned.

If a :buffer keyword argument is given and not nil:

*   The :buffer keyword should be a String, and will used as the output
    buffer. Using this option can reuse the memory required during
    inflation.
*   When not passing a block, the return value will be the same object
    as the :buffer keyword argument.
*   When passing a block, the yielded chunks will be the same value as
    the :buffer keyword argument.


Raises a Zlib::NeedDict exception if a preset dictionary is needed to
decompress.  Set the dictionary by Zlib::Inflate#set_dictionary and then
call this method again with an empty string to flush the stream:

    inflater = Zlib::Inflate.new

    begin
      out = inflater.inflate compressed
    rescue Zlib::NeedDict
      # ensure the dictionary matches the stream's required dictionary
      raise unless inflater.adler == Zlib.adler32(dictionary)

      inflater.set_dictionary dictionary
      inflater.inflate ''
    end

    # ...

    inflater.close
