ron
only.Expand description
Asserts a Serialize
snapshot in RON format.
Feature: ron
(disabled by default)
This works exactly like assert_yaml_snapshot!
but serializes in RON format instead of
YAML which retains some type information for more accurate comparisons.
Example:
assert_ron_snapshot!(vec![1, 2, 3]);
The third argument to the macro can be an object expression for redaction.
It’s in the form { selector => replacement }
. For more information
about redactions refer to the redactions feature in the guide.
The snapshot name is optional but can be provided as first argument.
