Package retag provides an ability to change tags of structures' fields in runtime

without copying of the data. It may be helpful in next cases:

* Automatic tags generation;

* Different views of the one data;

* Fixing of leaky abstractions with minimal boilerplate code

when application has layers of abstractions and model is

separated from storages and presentation layers.

Please see [examples in documentation](https://godoc.org/github.com/sevlyar/retag#example-package--Snaker) for details.

Features:

* No memory allocations (for cached types);

* Fast converting (lookup in table and pointer creation for cached types);

* Works with complex and nested types (e.g. `map[struct]*struct`).

The package requires go1.7+.
