Trait Implementations

impl<T: Clone + 'static> Clone for Expected<T>

fn clone(&self) -> Expected<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + 'static> Debug for Expected<T>

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

Formats the value using the given formatter.

impl<T: 'static> From<&'static [T]> for Expected<T>

fn from(value: &'static [T]) -> Self

Converts to this type from the input type.

impl<T: 'static> From<T> for Expected<T>

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: 'static> Index<usize> for Expected<T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'data, T: 'static> IntoIterator for &'data Expected<T>

type Item = &'data T

The type of the elements being iterated over.

type IntoIter = Iter<'data, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: PartialEq + 'static> PartialEq for Expected<T>

fn eq(&self, other: &Expected<T>) -> 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.

impl<T: Copy + 'static> Copy for Expected<T>

impl<T: Eq + 'static> Eq for Expected<T>

impl<T: 'static> StructuralPartialEq for Expected<T>
