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 OptChainBase: 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 OptChainBase: 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.

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 EqIgnoreSpan for OptChainBase

where V: Fold + ?Sized,

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

Calls Fold::fold_opt_chain_base with self.

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