Variants

SizedSelf(SmallVec<[Span; 1]>)

Self: Sized declared on the trait.

SupertraitSelf(SmallVec<[Span; 1]>)

SupertraitNonLifetimeBinder(SmallVec<[Span; 1]>)

Method(Symbol, MethodViolationCode, Span)

Method has something illegal.

AssocConst(Symbol, Span)

Associated const.

GAT(Symbol, Span)

Trait Implementations

impl<'tcx> ArenaAllocatable<'tcx, IsNotCopy> for ObjectSafetyViolation

fn allocate_on<'a>(self, arena: &'a Arena<'tcx>) -> &'a mut Self

fn allocate_from_iter<'a>( arena: &'a Arena<'tcx>, iter: impl IntoIterator<Item = Self> ) -> &'a mut [Self]

impl Clone for ObjectSafetyViolation

fn clone(&self) -> ObjectSafetyViolation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ObjectSafetyViolation

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

Formats the value using the given formatter.

impl Hash for ObjectSafetyViolation

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<'__ctx> HashStable<StableHashingContext<'__ctx>> for ObjectSafetyViolation

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher )

impl Ord for ObjectSafetyViolation

fn cmp(&self, other: &ObjectSafetyViolation) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ObjectSafetyViolation> for ObjectSafetyViolation

fn eq(&self, other: &ObjectSafetyViolation) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ObjectSafetyViolation> for ObjectSafetyViolation

fn partial_cmp(&self, other: &ObjectSafetyViolation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
