libmoox-struct-perl binary package in openKylin Yangtze V1.0 amd64

 MooX::Struct allows you to create cheap struct-like classes
 for your data using Moo.
 .
 While similar in spirit to MooseX::Struct and Class::Struct,
 MooX::Struct has a somewhat different usage pattern.
 Rather than providing you with a "struct" keyword
 which can be used to define structs,
 you define all the structs as part of the "use" statement.
 This means they happen at compile time.
 .
 A struct is just an "anonymous" Moo class.
 MooX::Struct creates this class for you,
 and installs a lexical alias for it in your namespace.
 Thus your module can create a "Point3D" struct,
 and some other module can too,
 and they won't interfere with each other.
 All struct classes inherit from MooX::Struct.
