# Freedom Models
[](https://crates.io/crates/freedom-models)
[](https://docs.rs/freedom-models/)
Contains data structures which map to Freedom resources to simplify usage
of the [Freedom API](https://github.com/ATLAS-Space-Operations/rust-freedom-api)
## HATEOAS Trait
In addition, the library exposes a single trait `Hateoas`. This is
useful for navigating the
[HATEOAS](https://en.wikipedia.org/wiki/HATEOAS) structure of the API.
## Unstable Flag
By default, all public structs in the crate are marked
`non_exhaustive`. This is because we may--at any time--add a field to
one or more of the structs, and this should not constitute a breaking
change for users.
However, for users who would like to construct the models for testing
purposes or as their baseline we do provide the `unstable` feature
flag, which disables this behavior when set.
By using the `unstable` flag you accept that your construction of
models might break between releases.
