Struct ExpectValue 

pub struct ExpectValue { /* private fields */ }

Implementations

impl ExpectValue

pub fn not(self) -> Self

pub fn soft(self) -> Self

pub fn with_message(self, message: impl Into<String>) -> Self

pub fn is_soft(&self) -> bool

pub fn actual(&self) -> &Value

pub fn to_be(&self, expected: &Value) -> Result<(), AssertionFailure>

toBe(expected) — strict-equality of primitives. Object/array values are rejected with guidance to use toEqual.

pub fn to_equal(&self, expected: &Value) -> Result<(), AssertionFailure>

toEqual(expected) — recursive equality. Honours asymmetric matchers embedded in expected.

pub fn to_strict_equal(&self, expected: &Value) -> Result<(), AssertionFailure>

toStrictEqual(expected) — alias of Self::to_equal for serde_json::Value (no undefined to differentiate).

pub fn to_be_null(&self) -> Result<(), AssertionFailure>

pub fn to_be_undefined(&self) -> Result<(), AssertionFailure>

toBeUndefined is satisfied by null because serde_json cannot distinguish — the QuickJS binding emits both as Value::Null.

pub fn to_be_defined(&self) -> Result<(), AssertionFailure>

pub fn to_be_truthy(&self) -> Result<(), AssertionFailure>

pub fn to_be_falsy(&self) -> Result<(), AssertionFailure>

pub fn to_be_nan(&self) -> Result<(), AssertionFailure>

pub fn to_be_close_to( &self, expected: f64, digits: Option<u8>, ) -> Result<(), AssertionFailure>

pub fn to_be_greater_than(&self, expected: f64) -> Result<(), AssertionFailure>

pub fn to_be_greater_than_or_equal( &self, expected: f64, ) -> Result<(), AssertionFailure>

pub fn to_be_less_than(&self, expected: f64) -> Result<(), AssertionFailure>

pub fn to_be_less_than_or_equal( &self, expected: f64, ) -> Result<(), AssertionFailure>

pub fn to_contain(&self, expected: &Value) -> Result<(), AssertionFailure>

toContain — primitive membership in array, substring in string.

pub fn to_contain_equal(&self, expected: &Value) -> Result<(), AssertionFailure>

Deep toContain — every element compared by deep_equal.

pub fn to_have_length(&self, expected: usize) -> Result<(), AssertionFailure>

pub fn to_have_property( &self, path: &Value, expected: Option<&Value>, ) -> Result<(), AssertionFailure>

toHaveProperty(path, value?) — path may be "a.b.c" or a JSON array of keys / indexes.

pub fn to_match(&self, pattern: &StringOrRegex) -> Result<(), AssertionFailure>

Jest’s toMatch(string) is substring containment; toMatch(/re/) is regex. Differs from StringOrRegex::matches (which is exact-equality for the string variant).

pub fn to_match_object(&self, subset: &Value) -> Result<(), AssertionFailure>

pub fn to_be_instance_of( &self, ctor_name: &str, actual_ctor_name: Option<&str>, ) -> Result<(), AssertionFailure>

toBeInstanceOf(ctorName) — checked against the binding-supplied constructor name (Class.name). When actual_ctor_name is None, falls back to the inferred built-in (e.g. Array for an array value).
