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> for ObjectSafetyViolation

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

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

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<(), Error>

Formats the value using the given formatter.

impl Hash for ObjectSafetyViolation

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

where __H: Hasher,

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<SipHasher128>, )

impl Ord for ObjectSafetyViolation

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ObjectSafetyViolation

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Eq for ObjectSafetyViolation

impl StructuralPartialEq for ObjectSafetyViolation

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
