Includes:
Farce::Shareable::Unfreezable
Defined in:
lib/farce/strict/lease_map.rb

Overview

A Ractor-shareable map that stores independently leased shareable resources directly. Initial resources, insertions, and replacements must be shareable. They are not automatically frozen. Other references remain usable, so callers must honor the checkout when accessing mutable resources.

Examples:

Updating shareable resources in an automatic lease scope

leases = Farce::Strict::LeaseMap.new do
  { primary: Farce::Strict::Map.new, replica: Farce::Strict::Map.new }
end
leases.auto_lease do
  leases[:primary][:status] = :ready
  leases[:replica][:status] = :ready
end
leases.checkout(:primary) { |state| state[:status] } # => :ready
