Enum Expectation 

#[non_exhaustive]
pub enum Expectation {
    Equals(Value),
    Regex(String),
    Contains(String),
    StartsWith(String),
    EndsWith(String),
    Exists,
    JsonSubset(Value),
    Any,
}

A validation expectation. The grammar keys mirror the mock-testkit matcher rules: equals, regex, contains, startsWith, endsWith, exists, jsonSubset.

Grammar (dual, value-style): a bare value is a literal equals; an object with exactly one recognized matcher key is that matcher (this reading takes precedence over the literal one); any other object — zero, multiple, or unrecognized keys — is a literal equals compared structurally. regex patterns are compile-verified at load time, matching the unit-tier matcher rules.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Equals(Value)

Exact equality against the value.

Regex(String)

Regular expression match, compile-verified at load time.

Contains(String)

Substring containment.

StartsWith(String)

Prefix match.

EndsWith(String)

Suffix match.

Exists

The value under validation is present.

JsonSubset(Value)

Recursive-subset match against an object.

Any

Matches any value including null; the wildcard verb (ignore at the grammar layer, the Citrus @ignore@ equivalent).
