The current status of GC profile mode.

Starts the GC profiler.

Returns whether the form contained multipart/form-data

Parses self destructively and returns self containing the rest arguments left unparsed.

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the year/month that it is planned to go away.

Is fetching of local and remote information enabled?

A Zlib::Inflate#inflate wrapper

SecureRandom.alphanumeric generates a random alphanumeric string.

The argument n specifies the length, in characters, of the alphanumeric string to be generated.

If n is not specified or is nil, 16 is assumed. It may be larger in the future.

The result may contain A-Z, a-z and 0-9.

require 'securerandom'

SecureRandom.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
SecureRandom.alphanumeric(10) #=> "i6K93NdqiH"

If a secure random number generator is not available, NotImplementedError is raised.

Returns true if JIT is enabled

@param [String] name @return [Object] the requirement that led to a version of a possibility

with the given name being activated.

@macro action

@return [String] the name of the source of explicit dependencies, i.e.

those passed to {Resolver#resolve} directly.

@return [String] the name of the source of ‘locked’ dependencies, i.e.

those passed to {Resolver#resolve} directly as the `base`

Load extra data embed into binary format String object.

Returns a new Array whose elements are the elements of self at the given Integer indexes.

For each positive index, returns the element at offset index:

a = [:foo, 'bar', 2]
a.values_at(0, 2) # => [:foo, 2]

The given indexes may be in any order, and may repeat:

a = [:foo, 'bar', 2]
a.values_at(2, 0, 1, 0, 2) # => [2, :foo, "bar", :foo, 2]

Assigns nil for an index that is too large:

a = [:foo, 'bar', 2]
a.values_at(0, 3, 1, 3) # => [:foo, nil, "bar", nil]

Returns a new empty Array if no arguments given.

For each negative index, counts backward from the end of the array:

a = [:foo, 'bar', 2]
a.values_at(-1, -3) # => [2, :foo]

Assigns nil for an index that is too small:

a = [:foo, 'bar', 2]
a.values_at(0, -5, 1, -6, 2) # => [:foo, nil, "bar", nil, 2]

The given indexes may have a mixture of signs:

a = [:foo, 'bar', 2]
a.values_at(0, -2, 1, -1) # => [:foo, "bar", "bar", 2]

Deletes an element from self, per the given Integer index.

When index is non-negative, deletes the element at offset index:

a = [:foo, 'bar', 2]
a.delete_at(1) # => "bar"
a # => [:foo, 2]

If index is too large, returns nil.

When index is negative, counts backward from the end of the array:

a = [:foo, 'bar', 2]
a.delete_at(-2) # => "bar"
a # => [:foo, 2]

If index is too small (far from zero), returns nil.
