Trait Implementations

impl ASTNode for GenericTypeConstraint

fn from_reader( reader: &mut impl TokenReader<TSXToken, Span>, 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) -> Cow<'_, Span>

Returns position of node as span AS IT WAS PARSED. May be none if AST was doesn’t match anything in source

fn from_string( source: String, settings: ParseOptions, source_id: SourceId, offset: Option<usize>, cursors: Vec<(usize, EmptyCursorId)> ) -> 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 GenericTypeConstraint

fn clone(&self) -> GenericTypeConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericTypeConstraint

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

Formats the value using the given formatter.

impl PartialEq<GenericTypeConstraint> for GenericTypeConstraint

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

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

fn to_tokens(&self) -> TokenStream

Returns the tokens used to construct self
