Panics

Panics if the value is not Call, with a panic message including the content of self.

pub fn call(self) -> Option<OptCall>

Available on crate feature ecma_ast only.

Returns Some if self is of variant Call, and None otherwise.

Trait Implementations

impl Archive for OptChainBase

type Archived = ArchivedOptChainBase

The archived representation of this type.

type Resolver = OptChainBaseResolver

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

fn resolve( &self, resolver: <OptChainBase as Archive>::Resolver, out: Place<<OptChainBase as Archive>::Archived>, )

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

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for OptChainBase

fn clone(&self) -> OptChainBase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OptChainBase

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

Formats the value using the given formatter.

impl Default for OptChainBase

fn default() -> OptChainBase

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for OptChainBase

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<OptChainBase, __D> for <OptChainBase as Archive>::Archived

where __D: Fallible + ?Sized, <__D as Fallible>::Error: Source,

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

Deserializes using the given deserializer

impl<V> FoldWith<V> for OptChainBase

where V: Fold + ?Sized,

fn fold_with(self, visitor: &mut V) -> OptChainBase

Calls Fold::fold_opt_chain_base with self.

Visit children nodes of self`` with visitor`.

impl<'ast> From<&'ast OptChainBase> for NodeRef<'ast>

fn from(node: &'ast OptChainBase) -> NodeRef<'ast>

Converts to this type from the input type.

impl From<MemberExpr> for OptChainBase

fn from(v: MemberExpr) -> OptChainBase

Converts to this type from the input type.

impl From<OptCall> for OptChainBase

fn from(v: OptCall) -> OptChainBase

Converts to this type from the input type.

impl From<OptChainBase> for Expr

fn from(opt: OptChainBase) -> Expr

Converts to this type from the input type.

impl PartialEq for OptChainBase

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

Tests for self and other values to be equal, and is used by ==.

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