Struct Assertion 

pub struct Assertion {
    pub assertion_type: String,
    pub field: Option<String>,
    pub value: Option<Value>,
    pub values: Option<Vec<Value>>,
    pub method: Option<String>,
    pub check: Option<String>,
    pub args: Option<Value>,
    pub return_type: Option<String>,
}

A single assertion in a fixture.

Fields

assertion_type: String

Assertion type (equals, contains, not_empty, error, etc.).

field: Option<String>

Field path to access on the result (dot-separated).

value: Option<Value>

Expected value (string, number, bool, or array depending on type).

values: Option<Vec<Value>>

Expected values (for contains_all, contains_any).

method: Option<String>

Method name to call on the result (for method_result assertions).

check: Option<String>

Assertion check type for the method result (equals, is_true, is_false, greater_than_or_equal, count_min).

args: Option<Value>

Arguments to pass to the method call (for method_result assertions).

return_type: Option<String>

Return type hint for C method_result codegen.

Supported values:

• "string" — the method returns a heap-allocated char* that must be freed with free() after the assertion. The generator emits char* _r = call(); assert(...); free(_r);.

Defaults to primitive integer dispatch when absent.

Trait Implementations

impl Clone for Assertion

fn clone(&self) -> Assertion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Assertion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Assertion

fn default() -> Assertion

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Assertion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Assertion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
