The UriFormatter
handles URIs from user-input and escaping.
uf = Gem::UriFormatter.new 'example.com' p uf.normalize #=> 'http://example.com'
Raised by Timeout.timeout
when the block times out.
Base class for all URI
exceptions.
Not a URI
.
Not a URI
component.
URI
is valid, bad usage is not.
Class
that parses String’s into URI’s.
It contains a Hash
set of patterns and Regexp’s that match and validate.
RefError
is raised when a referenced object has been recycled by the garbage collector
Raised when a mathematical function is evaluated outside of its domain of definition.
For example, since cos
returns values in the range -1..1, its inverse function acos
is only defined on that interval:
Math.acos(42)
produces:
Math::DomainError: Numerical argument is out of domain - "acos"
Raised on attempt to Ractor#take
if there was an uncaught exception in the Ractor
. Its cause
will contain the original exception, and ractor
is the original ractor it was raised in.
r = Ractor.new { raise "Something weird happened" } begin r.take rescue => e p e # => #<Ractor::RemoteError: thrown by remote Ractor.> p e.ractor == r # => true p e.cause # => #<RuntimeError: Something weird happened> end
Raised on an attempt to access an object which was moved in Ractor#send
or Ractor.yield
.
r = Ractor.new { sleep } ary = [1, 2, 3] r.send(ary, move: true) ary.inspect # Ractor::MovedError (can not send any methods to a moved object)
Raised by Encoding
and String
methods when the string being transcoded contains a byte invalid for the either the source or target encoding.
A mixin that provides methods for parsing C struct and prototype signatures.
require 'fiddle/import' include Fiddle::CParser #=> Object parse_ctype('int') #=> Fiddle::TYPE_INT parse_struct_signature(['int i', 'char c']) #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]] parse_signature('double sum(double, double)') #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]]
A DSL that provides the means to dynamically load libraries and build modules around them including calling extern functions within the C library that has been loaded.
require 'fiddle' require 'fiddle/import' module LibSum extend Fiddle::Importer dlload './libsum.so' extern 'double sum(double*, int)' extern 'double split(double)' end
Used to construct C classes (CUnion
, CStruct
, etc)
Fiddle::Importer#struct
and Fiddle::Importer#union
wrap this functionality in an easy-to-use manner.
OpenSSL
IO
buffering mix-in module.
This module allows an OpenSSL::SSL::SSLSocket
to behave like an IO
.
You typically won’t use this module directly, you can see it implemented in OpenSSL::SSL::SSLSocket
.
The GC
profiler provides access to information on GC
runs including time, length and object space size.
Example:
GC::Profiler.enable require 'rdoc/rdoc' GC::Profiler.report GC::Profiler.disable
See also GC.count
, GC.malloc_allocated_size
and GC.malloc_allocations
Mixin module that provides the following:
Access to the CGI
environment variables as methods. See documentation to the CGI
class for a list of these variables. The methods are exposed by removing the leading HTTP_
(if it exists) and downcasing the name. For example, auth_type
will return the environment variable AUTH_TYPE
, and accept
will return the value for HTTP_ACCEPT
.
Access to cookies, including the cookies attribute.
Access to parameters, including the params attribute, and overloading []
to perform parameter value lookup by key.
The initialize_query
method, for initializing the above mechanisms, handling multipart forms, and allowing the class to be used in “offline” mode.
