Struct TestObserver 

pub struct TestObserver<V: Debug + PartialEq> { /* private fields */ }

An observer that can be used to observe values from a HangingGet or Window instance. The observer must not be observed multiple times without the value being taken with take_value inbetween each observation. This prevents overwriting observations without checking them and simplifies the logic and API surface of this fake.

Implementations

impl<V: Debug + Clone + Send + PartialEq> TestObserver<V>

pub fn new() -> Self

pub fn expect_value(expected: V) -> Self

pub fn expect_no_value() -> Self

pub fn observe(v: &V, o: Self) -> bool

pub fn observe_incomplete(v: &V, o: Self) -> bool

pub fn has_value(&self) -> bool

Trait Implementations

impl<V: Clone + Debug + PartialEq> Clone for TestObserver<V>

fn clone(&self) -> TestObserver<V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug + Debug + PartialEq> Debug for TestObserver<V>

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

Formats the value using the given formatter.

impl<V: Debug + PartialEq> Drop for TestObserver<V>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<V: PartialEq + Debug + PartialEq> PartialEq for TestObserver<V>

fn eq(&self, other: &TestObserver<V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
