Trait Implementations

impl Archive for ReferentialAction

type Archived = ArchivedReferentialAction

The archived representation of this type.

type Resolver = ReferentialActionResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <Self as Archive>::Resolver, out: *mut <Self as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for ReferentialAction

fn clone(&self) -> ReferentialAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferentialAction

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ReferentialAction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D: Fallible + ?Sized> Deserialize<ReferentialAction, __D> for Archived<ReferentialAction>

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ReferentialAction, __D::Error>

Deserializes using the given deserializer

impl PartialEq for ReferentialAction

fn eq(&self, other: &ReferentialAction) -> 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<__S: Fallible + ?Sized> Serialize<__S> for ReferentialAction

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, __S::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Serialize for ReferentialAction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
