Types
A format representing how a single key should be mapped from a source. The actual format is a 2 element tuple
Functions
Takes a source map and a list of tuples representing how the source map should be transformed into a new map, then applies the mapping operation on each field
Performs the inverse of &transform/2

A format representing how a single key should be mapped from a source. The actual format is a 2 element tuple.
The first element is the destination key in the output map.
The second element is a list of keys representing the nested path to the key in the source map.
For example, the tuple:
{:target_path, ["nested", "path", "to", "source"]}
Means that, from the source map, we need to take the nested value under “nested” => “path” => “to” => “source” and then put it into the output map, as a value for the key “:target_path”.

transform(map(), mapping()) :: map()
Takes a source map and a list of tuples representing how the source map should be transformed into a new map, then applies the mapping operation on each field.
transform_inverse(map(), mapping()) :: map()
