Implementations

impl OptChainBase

pub 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) -> MemberExprwhere
    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 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) -> OptCallwhere
    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 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<'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 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.

impl Hash for OptChainBase

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,

Feeds a slice of this type into the given Hasher.

impl PartialEq<OptChainBase> for OptChainBase

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

fn span_hi(&self) -> BytePos

impl Take for OptChainBase

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,
