Trait Implementations

impl Clone for ParameterData

fn clone(&self) -> ParameterData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParameterData

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

Formats the value using the given formatter.

impl PartialEq for ParameterData

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

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 ParameterData

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 ParameterData

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

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