(untyped obj) -> bool

Ractor.shareable?(obj) → true | false

# File tmp/rubies/ruby-4.0.0/ractor.rb, line 418
def self.shareable? obj
  __builtin_cexpr! %q{
    RBOOL(rb_ractor_shareable_p(obj));
  }
end

Checks if the object is shareable by ractors.

Example

Ractor.shareable?(1)            #=> true -- numbers are shareable
Ractor.shareable?('foo')        #=> false, unless the string is frozen due to # frozen_string_literal: true
Ractor.shareable?('foo'.freeze) #=> true
