Reasons a method might not be dyn-compatible.

Variants

StaticMethod(Option<((String, Span), (String, Span))>)

e.g., fn foo()

ReferencesSelfInput(Option<Span>)

e.g., fn foo(&self, x: Self)

ReferencesSelfOutput

e.g., fn foo(&self) -> Self

ReferencesImplTraitInTrait(Span)

e.g., fn foo(&self) -> impl Sized

AsyncFn

e.g., async fn foo(&self)

WhereClauseReferencesSelf

e.g., fn foo(&self) where Self: Clone

Generic

e.g., fn foo<A>()

UndispatchableReceiver(Option<Span>)

the method’s receiver (self argument) can’t be dispatched on

Trait Implementations

impl Clone for MethodViolationCode

fn clone(&self) -> MethodViolationCode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MethodViolationCode

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

Formats the value using the given formatter.

impl Hash for MethodViolationCode

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 MethodViolationCode

fn hash_stable( &self, __hcx: &mut StableHashingContext<'__ctx>, __hasher: &mut StableHasher<SipHasher128>, )

impl Ord for MethodViolationCode

fn cmp(&self, other: &MethodViolationCode) -> 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,

Restrict a value to a certain interval.

impl PartialEq for MethodViolationCode

fn eq(&self, other: &MethodViolationCode) -> 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 MethodViolationCode

fn partial_cmp(&self, other: &MethodViolationCode) -> 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 MethodViolationCode

impl StructuralPartialEq for MethodViolationCode

Layout

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.
