Implementations§

source§

impl ParameterChange

source

pub fn encode_parameters(parameters: Value) -> Self

Generates a set of encoded parameters for the given object.

This is useful for generating template changes.

source

pub fn apply_changes_raw(&self, app_parameters: Value) -> Result<Value, Error>

Applies a set of changes to the “raw” app parameters.

The app parameters are input as a serde_json::Value object, so that the parameter change code does not need to know about the structure of the entire application.

If the changes can be successfully applied, the new app parameters are returned. By taking ownership of the input app_parameters, we ensure that the caller cannot access any partially-mutated app parameters in the event of an error applying one of them.
