Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for OptChainExpr

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Archive for OptChainExpr

type Archived = ArchivedOptChainExpr

The archived representation of this type.

type Resolver = OptChainExprResolver

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::Resolver, out: *mut Self::Archived )

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

impl AstNode for OptChainExpr

const TYPE: &'static str = "OptionalChainingExpression"

impl Clone for OptChainExpr

fn clone(&self) -> OptChainExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptChainExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for OptChainExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<OptChainExpr, __D> for Archived<OptChainExpr>where __D: SharedDeserializeRegistry + Fallible + ?Sized,

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

Deserializes using the given deserializer

impl EqIgnoreSpan for OptChainExpr

fn eq_ignore_span(&self, other: &Self) -> bool

impl From<OptChainExpr> for Box<Expr>

fn from(src: OptChainExpr) -> Box<Expr>

Converts to this type from the input type.

impl From<OptChainExpr> for Expr

fn from(v: OptChainExpr) -> Self

Converts to this type from the input type.

impl From<OptChainExpr> for PatOrExpr

fn from(src: OptChainExpr) -> PatOrExpr

Converts to this type from the input type.

impl Hash for OptChainExpr

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 PartialEq<OptChainExpr> for OptChainExpr

fn eq(&self, other: &OptChainExpr) -> 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<__S> Serialize<__S> for OptChainExprwhere __S: Serializer + ScratchSpace + SharedSerializeRegistry + Fallible + ?Sized,

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

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

impl Serialize for OptChainExpr

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

Serialize this value into the given Serde serializer.

impl Spanned for OptChainExpr

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Take for OptChainExpr

fn dummy() -> Self

Create a dummy value of this type.

fn take(&mut self) -> Self

fn map_with_mut<F>(&mut self, op: F)where F: FnOnce(Self) -> Self,

Mutate self using op, which accepts owned data.
