The superclass for all exceptions raised by Ruby/zlib.
The following exceptions are defined as subclasses of Zlib::Error. These exceptions are raised when zlib library functions return with an error status.
Subclass of Zlib::Error when zlib returns a Z_DATA_ERROR.
Usually if a stream was prematurely freed.
Subclass of Zlib::Error
When zlib returns a Z_MEM_ERROR, usually if there was not enough memory.
Subclass of Zlib::Error when zlib returns a Z_BUF_ERROR.
Usually if no progress is possible.
Subclass of Zlib::Error
When zlib returns a Z_VERSION_ERROR, usually if the zlib library version is incompatible with the version assumed by the caller.
Zlib::GzipReader is the class for reading a gzipped file. GzipReader should be used as an IO, or -IO-like, object.
Zlib::GzipReader.open('hoge.gz') {|gz| print gz.read } File.open('hoge.gz') do |f| gz = Zlib::GzipReader.new(f) print gz.read gz.close end
Method Catalogue The following methods in Zlib::GzipReader are just like their counterparts in IO, but they raise Zlib::Error or Zlib::GzipFile::Error exception if an error was found in the gzip file.
Be careful of the footer of the gzip file. A gzip file has the checksum of pre-compressed data in its footer. GzipReader checks all uncompressed data against that checksum at the following cases, and if it fails, raises Zlib::GzipFile::NoFooter, Zlib::GzipFile::CRCError, or Zlib::GzipFile::LengthError exception.
When an reading request is received beyond the end of file (the end of compressed data). That is, when Zlib::GzipReader#read, Zlib::GzipReader#gets, or some other methods for reading returns nil.
When Zlib::GzipFile#close method is called after the object reaches the end of file.
When Zlib::GzipReader#unused method is called after the object reaches the end of file.
The rest of the methods are adequately described in their own documentation.
Objects of class File::Stat encapsulate common status information for File objects. The information is recorded at the moment the File::Stat object is created; changes made to the file after that point will not be reflected. File::Stat objects are returned by IO#stat, File::stat, File#lstat, and File::lstat. Many of these methods return platform-specific values, and not all values are meaningful on all systems. See also Kernel#test.
exception to wait for reading by EAGAIN. see IO.select.
exception to wait for reading by EWOULDBLOCK. see IO.select.
exception to wait for writing by EINPROGRESS. see IO.select.
The InstructionSequence class represents a compiled sequence of instructions for the Ruby Virtual Machine.
With it, you can get a handle to the instructions that make up a method or a proc, compile strings of Ruby code down to VM instructions, and disassemble instruction sequences to strings for easy inspection. It is mostly useful if you want to learn how the Ruby VM works, but it also lets you control various settings for the Ruby iseq compiler.
You can find the source for the VM instructions in insns.def in the Ruby source.
The instruction sequence results will almost certainly change as Ruby changes, so example output in this documentation may be different from what you see.

Superclass of all errors raised in the DRb module.
Error raised when an error occurs on the underlying communication protocol.
An exception wrapping a DRb::DRbUnknown object
The default drb protocol which communicates over a TCP socket.
The DRb TCP protocol URI looks like: druby://<host>:<port>?<option>. The option is optional.
Error types.
A custom InputMethod class used by XMP for evaluating string io.
Default formatter for log messages.
