Implementations

impl PropOrSpread

pub fn is_spread(&self) -> bool

Returns true if self is of variant Spread.

pub fn as_spread(&self) -> Option<&SpreadElement>

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

pub fn as_mut_spread(&mut self) -> Option<&mut SpreadElement>

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

pub fn expect_spread(self) -> SpreadElementwhere Self: Debug,

Unwraps the value, yielding the content of Spread.

Panics

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

pub fn spread(self) -> Option<SpreadElement>

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

pub fn is_prop(&self) -> bool

Returns true if self is of variant Prop.

pub fn as_prop(&self) -> Option<&Box<Prop>>

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

pub fn as_mut_prop(&mut self) -> Option<&mut Box<Prop>>

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

pub fn expect_prop(self) -> Box<Prop>where Self: Debug,

Unwraps the value, yielding the content of Prop.

Panics

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

pub fn prop(self) -> Option<Box<Prop>>

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

Trait Implementations

impl Archive for PropOrSpread

type Archived = ArchivedPropOrSpread

The archived representation of this type.

type Resolver = PropOrSpreadResolver

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 PropOrSpread

fn clone(&self) -> PropOrSpread

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PropOrSpread

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PropOrSpread

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

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<PropOrSpread, __D> for Archived<PropOrSpread>where __D: SharedDeserializeRegistry + Fallible + ?Sized,

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

Deserializes using the given deserializer

impl EqIgnoreSpan for PropOrSpread

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

impl From<Box<Prop, Global>> for PropOrSpread

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

Converts to this type from the input type.

impl From<Prop> for PropOrSpread

fn from(src: Prop) -> PropOrSpread

Converts to this type from the input type.

impl From<SpreadElement> for PropOrSpread

fn from(v: SpreadElement) -> Self

Converts to this type from the input type.

impl Hash for PropOrSpread

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<PropOrSpread> for PropOrSpread

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

impl<__S> Serialize<__S> for PropOrSpreadwhere __S: Serializer + ScratchSpace + SharedSerializeRegistry + 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 PropOrSpread

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 PropOrSpread

fn span(&self) -> Span

Get span of self.

fn span_lo(&self) -> BytePos

fn span_hi(&self) -> BytePos

impl Take for PropOrSpread

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.
