Implementations

impl VarDeclOrExpr

pub const fn is_var_decl(&self) -> bool

Returns true if self is of variant VarDecl.

pub fn as_var_decl(&self) -> Option<&Box<VarDecl>>

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

pub fn as_mut_var_decl(&mut self) -> Option<&mut Box<VarDecl>>

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

pub fn expect_var_decl(self) -> Box<VarDecl>

where Self: Debug,

Unwraps the value, yielding the content of VarDecl.

Panics

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

pub fn var_decl(self) -> Option<Box<VarDecl>>

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

pub const fn is_expr(&self) -> bool

Returns true if self is of variant Expr.

pub fn as_expr(&self) -> Option<&Box<Expr>>

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

pub fn as_mut_expr(&mut self) -> Option<&mut Box<Expr>>

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

pub fn expect_expr(self) -> Box<Expr>

where Self: Debug,

Unwraps the value, yielding the content of Expr.

Panics

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

pub fn expr(self) -> Option<Box<Expr>>

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

Trait Implementations

impl Archive for VarDeclOrExpr

type Archived = ArchivedVarDeclOrExpr

The archived representation of this type.

type Resolver = VarDeclOrExprResolver

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 VarDeclOrExpr

fn clone(&self) -> VarDeclOrExpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VarDeclOrExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VarDeclOrExpr

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<VarDeclOrExpr, __D> for Archived<VarDeclOrExpr>

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

Deserializes using the given deserializer

impl EqIgnoreSpan for VarDeclOrExpr

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

impl From<Box<Expr>> for VarDeclOrExpr

fn from(v: Box<Expr>) -> Self

Converts to this type from the input type.

impl From<Box<VarDecl>> for VarDeclOrExpr

fn from(v: Box<VarDecl>) -> Self

Converts to this type from the input type.

impl From<Expr> for VarDeclOrExpr

fn from(src: Expr) -> VarDeclOrExpr

Converts to this type from the input type.

impl From<VarDecl> for VarDeclOrExpr

fn from(src: VarDecl) -> VarDeclOrExpr

Converts to this type from the input type.

impl Hash for VarDeclOrExpr

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 for VarDeclOrExpr

fn eq(&self, other: &VarDeclOrExpr) -> 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 VarDeclOrExpr

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

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

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

impl Serialize for VarDeclOrExpr

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 VarDeclOrExpr

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Take for VarDeclOrExpr

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.
