Macro insta::assert_ron_snapshot

macro_rules! assert_ron_snapshot {
    ($value : expr, @ $snapshot : literal) => { ... };
    ($value : expr, { $($k : expr => $v : expr), * $(,) ? }, @ $snapshot :
 literal) => { ... };
    ($value : expr, { $($k : expr => $v : expr), * $(,) ? }) => { ... };
    ($name : expr, $value : expr) => { ... };
    ($name : expr, $value : expr, { $($k : expr => $v : expr), * $(,) ? }) => { ... };

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 comparisions.

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.
