Reference documentation and code samples for the Google Cloud Platform environment queries class Google::Cloud::Env::Variables.
Access to system environment variables.
This is a hashlike object that controls access to environment variable data. It supports temporarily changing the data source (i.e. swapping ::ENV out for a different set of data) for mocking.

The backing data is a hash or hash-like object that represents the environment variable data. This can either be the actual environment variables object (i.e. ENV) or a substitute hash used for mocking.

(
temp_backing_data
)
Run the given block with the backing data replaced with the given hash. The original backing data is restored afterward. This is used for debugging/testing/mocking.
- temp_backing_data(Hash{String=>String})
