Implementations

impl OptChainBase

pub const fn is_member(&self) -> bool

Returns true if self is of variant Member.

pub fn as_member(&self) -> Option<&MemberExpr>

Returns Some if self is a reference of variant Member, and None otherwise.

pub fn as_mut_member(&mut self) -> Option<&mut MemberExpr>

Returns Some if self is a mutable reference of variant Member, and None otherwise.

pub fn expect_member(self) -> MemberExpr

where Self: Debug,

Unwraps the value, yielding the content of Member.

Panics

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

pub fn member(self) -> Option<MemberExpr>

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

pub const fn is_call(&self) -> bool

Returns true if self is of variant Call.

pub fn as_call(&self) -> Option<&OptCall>

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

pub fn as_mut_call(&mut self) -> Option<&mut OptCall>

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

pub fn expect_call(self) -> OptCall

where Self: Debug,

Unwraps the value, yielding the content of Call.

Panics

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

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

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

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for OptChainBase

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.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

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

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.

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 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

Formats the value using the given formatter.

impl Default for OptChainBase

fn default() -> Self

Returns the “default value” for a type.

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

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<OptChainBase, __D> for Archived<OptChainBase>

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

Deserializes using the given deserializer

impl EqIgnoreSpan for OptChainBase

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

impl From<MemberExpr> for OptChainBase

fn from(v: MemberExpr) -> Self

Converts to this type from the input type.

impl From<OptCall> for OptChainBase

fn from(v: OptCall) -> Self

Converts to this type from the input type.

impl From<OptChainBase> for Expr

fn from(opt: OptChainBase) -> Self

Converts to this type from the input type.

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<__S> Serialize<__S> for OptChainBase

where __S: ScratchSpace + Serializer + Fallible + ?Sized,

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