Trait Implementations

impl ASTNode for IsExpression

fn from_reader( reader: &mut impl TokenReader<TSXToken, TokenStart>, state: &mut ParsingState, settings: &ParseOptions ) -> ParseResult<Self>

fn to_string_from_buffer<T: ToString>( &self, buf: &mut T, settings: &ToStringOptions, depth: u8 )

fn get_position(&self) -> &Span

Returns position of node as span AS IT WAS PARSED. May be Span::NULL if AST was doesn’t match anything in source

fn from_string( script: String, options: ParseOptions, source: SourceId, offset: Option<u32> ) -> ParseResult<Self>

From string, with default impl to call abstract method from_reader

fn to_string(&self, settings: &ToStringOptions) -> String

Returns structure as valid string

impl Clone for IsExpression

fn clone(&self) -> IsExpression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IsExpression

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

Formats the value using the given formatter.

impl GetFieldByType<BaseSpan<()>> for IsExpression

fn get(&self) -> &Span

Get the value of a field that has type T

impl PartialEq for IsExpression

fn eq(&self, other: &IsExpression) -> 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 SelfRustTokenize for IsExpression

fn append_to_token_stream(&self, token_stream: &mut TokenStream)

fn to_tokens(&self) -> TokenStream

Returns the tokens used to construct self

impl Serialize for IsExpression

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Visitable for IsExpression

fn visit<TData>( &self, visitors: &mut (impl VisitorReceiver<TData> + ?Sized), data: &mut TData, settings: &VisitSettings, chain: &mut Annex<'_, Chain> )

fn visit_mut<TData>( &mut self, visitors: &mut (impl VisitorMutReceiver<TData> + ?Sized), data: &mut TData, settings: &VisitSettings, chain: &mut Annex<'_, Chain> )
