module PackedStruct

Called when this is included into another module.

@api private @param reciever [Module] the reciever that included this one. @return [void]

# File lib/packed_struct.rb, line 44
def self.included(reciever)
  reciever.extend self
end

Define a struct. The name will be used for {#structs}, and the block will run in the context of a {Package}.

@yield [] @param name [Symbol, nil] the name of the struct. If it’s nil, it

is set as the only struct of the included module.

@return (see structs)

# File lib/packed_struct.rb, line 27
def struct_layout(name = nil, &block)
  structs[name] = Package.new
  structs[name].instance_exec &block
  structs[name].finalize_directives!

  if name == nil
    @structs = structs[name]
  end

  structs
end

The structs that were defined on the module that included this. If the structs were defined without a name, this will be the one and only struct that was defined (or the last one that was defined).

@return [Package, Hash<Symbol, Package>]

# File lib/packed_struct.rb, line 14
def structs
  @structs ||= {}
