Path Validation

Some plugins specify a path within the source data. A path is simply an array of keys to be traversed within the source tree. The following options are added by this trait:

path

The array of keys used to specify the path in the source data.

current_value

The optional current value in the config data path. Used to ensure that the specified value exists in the data before manipulating it. This must be specified to enable path validation.

value_path

An optional path to be used instead of the normal path for validating the current_value. Used when changing the value in path but testing current_value in a different value_path.
