 ## JSONCompatible
 <div class='class-sig' id='prefect-utilities-serialization-jsoncompatible'><p class="prefect-sig">class </p><p class="prefect-class">prefect.utilities.serialization.JSONCompatible</p>(*args, **kwargs)<span class="source"><a href="https://github.com/PrefectHQ/prefect/blob/master/src/prefect/utilities/serialization.py#L164">[source]</a></span></div>

Field that ensures its values are JSON-compatible during serialization and deserialization

**Args**:     <ul class="args"><li class="args">`*args (Any)`: the arguments accepted by `marshmallow.Field`     </li><li class="args">`**kwargs (Any)`: the keyword arguments accepted by `marshmallow.Field`</li></ul>

 ## Nested
 <div class='class-sig' id='prefect-utilities-serialization-nested'><p class="prefect-sig">class </p><p class="prefect-class">prefect.utilities.serialization.Nested</p>(nested, value_selection_fn, **kwargs)<span class="source"><a href="https://github.com/PrefectHQ/prefect/blob/master/src/prefect/utilities/serialization.py#L188">[source]</a></span></div>

An extension of the Marshmallow Nested field that allows the value to be selected via a value_selection_fn.

Note that because the value_selection_fn is always called, users must return `marshmallow.missing` if they don't want this field included in the resulting serialized object.

**Args**:     <ul class="args"><li class="args">`nested (type)`: the nested schema class     </li><li class="args">`value_selection_fn (Callable)`: a function that is called whenever the object is serialized,         to retrieve the object (if not available as a simple attribute of the parent schema)     </li><li class="args">`**kwargs (Any)`: the keyword arguments accepted by `marshmallow.Field`</li></ul>

 ## Bytes

A Marshmallow Field that serializes bytes to a base64-encoded string, and deserializes a base64-encoded string to bytes.

**Args**:     <ul class="args"><li class="args">`*args (Any)`: the arguments accepted by `marshmallow.Field`     </li><li class="args">`**kwargs (Any)`: the keyword arguments accepted by `marshmallow.Field`</li></ul>

 ## UUID

Replacement for fields.UUID that performs validation but returns string objects, not UUIDs

**Args**:     <ul class="args"><li class="args">`*args (Any)`: the arguments accepted by `marshmallow.Field`     </li><li class="args">`**kwargs (Any)`: the keyword arguments accepted by `marshmallow.Field`</li></ul>

 ## FunctionReference
 <div class='class-sig' id='prefect-utilities-serialization-functionreference'><p class="prefect-sig">class </p><p class="prefect-class">prefect.utilities.serialization.FunctionReference</p>(valid_functions, reject_invalid=True, **kwargs)<span class="source"><a href="https://github.com/PrefectHQ/prefect/blob/master/src/prefect/utilities/serialization.py#L294">[source]</a></span></div>

Field that stores a reference to a function as a string and reloads it when deserialized.

**Args**:     <ul class="args"><li class="args">`valid_functions (List[Callable])`: a list of functions that will be serialized as string         references     </li><li class="args">`reject_invalid (bool)`: if True, functions not in `valid_functions` will be rejected. If False,         any value will be allowed, but only functions in `valid_functions` will be deserialized.     </li><li class="args">`**kwargs (Any)`: the keyword arguments accepted by `marshmallow.Field`</li></ul>
