Return the receiver associated with this KeyError exception.
Return the receiver associated with this NameError exception.
Return the receiver associated with this FrozenError exception.
Returns an array of Refinement defined within the receiver.
module A refine Integer do end refine String do end end p A.refinements
produces:
[#<refinement:Integer@A>, #<refinement:String@A>]
Returns true if range overlaps with self, false otherwise:
(0..2).overlap?(1..3) #=> true (0..2).overlap?(3..4) #=> false (0..).overlap?(..0) #=> true
With non-range argument, raises TypeError.
(1..3).overlap?(1) # TypeError
Returns false if an internal call to <=> returns nil; that is, the operands are not comparable.
(1..3).overlap?('a'..'d') # => false
Returns false if self or range is empty. “Empty range” means that its begin value is larger than, or equal for an exclusive range, its end value.
(4..1).overlap?(2..3) # => false (4..1).overlap?(..3) # => false (4..1).overlap?(2..) # => false (2...2).overlap?(1..2) # => false (1..4).overlap?(3..2) # => false (..4).overlap?(3..2) # => false (1..).overlap?(3..2) # => false (1..2).overlap?(2...2) # => false
Returns false if the begin value one of self and range is larger than, or equal if the other is an exclusive range, the end value of the other:
(4..5).overlap?(2..3) # => false (4..5).overlap?(2...4) # => false (1..2).overlap?(3..4) # => false (1...3).overlap?(3..4) # => false
Returns false if the end value one of self and range is larger than, or equal for an exclusive range, the end value of the other:
(4..5).overlap?(2..3) # => false (4..5).overlap?(2...4) # => false (1..2).overlap?(3..4) # => false (1...3).overlap?(3..4) # => false
Note that the method wouldn’t make any assumptions about the beginless range being actually empty, even if its upper bound is the minimum possible value of its type, so all this would return true:
(...-Float::INFINITY).overlap?(...-Float::INFINITY) # => true (..."").overlap?(..."") # => true (...[]).overlap?(...[]) # => true
Even if those ranges are effectively empty (no number can be smaller than -Float::INFINITY), they are still considered overlapping with themselves.

The opposite of Pathname#absolute?
It returns false if the pathname begins with a slash.
p = Pathname.new('/im/sure') p.relative? #=> false p = Pathname.new('not/so/sure') p.relative? #=> true
Returns a string for DNS reverse lookup. It returns a string in RFC3172 form for an IPv6 address.
Returns the bound receiver of the binding object.
Returns the bound receiver of the method object.
(1..3).method(:map).receiver # => 1..3
Receive a message from the default port.
same as Ractor.receive
When RubyGems is required, Kernel#require is replaced with our own which is capable of loading gems on demand.
When you call require 'x', this is what happens:
If the file can be loaded from the existing Ruby loadpath, it is.
Otherwise, installed gems are searched for a file that matches. If it’s found in gem ‘y’, that gem is activated (added to the loadpath).
The normal require functionality of returning false if that file has already been loaded is preserved.
Refresh available gems from disk.
Returns location objects associated with the AST node. The returned array contains RubyVM::AbstractSyntaxTree::Location.
Gets various OpenSSL options.
Sets various OpenSSL options. The options are a bit field and can be combined with the bitwise OR operator (|). Available options are defined as constants in OpenSSL::SSL that begin with OP_.
For backwards compatibility, passing nil has the same effect as passing OpenSSL::SSL::OP_ALL.
See also man page SSL_CTX_set_options(3).
Initiates an SSL/TLS handshake with a server.
Configure the columns field for this repository and return self.
A list of file names contained in this gem
True if the requested gem has already been installed.
Installing a git gem only involves building the extensions and generating the executables.
