Trait Implementations

impl<T: Clone> Clone for Dummy<T>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Dummy<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Dummy<T>

fn default() -> Dummy<T>

Returns the “default value” for a type.

impl<T> ForeachTarget for Dummy<T>

type JumpTarget = T

fn foreach_target<F>(&self, _f: F)

where F: FnMut(&Self::JumpTarget),

fn foreach_target_mut<F>(&mut self, _f: F)

where F: FnMut(&mut Self::JumpTarget),

impl<T: Hash> Hash for Dummy<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq for Dummy<T>

fn eq(&self, other: &Dummy<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> Copy for Dummy<T>

impl<T: Eq> Eq for Dummy<T>

impl<T> StructuralPartialEq for Dummy<T>
