Struct rune::MacroContext [−][src]
Context for a running macro.
Implementations
impl MacroContext[src]
pub fn empty() -> Self[src]
Construct an empty macro context. Should only be used for testing.
pub fn resolve_owned<T>(&self, item: T) -> Result<T::Owned, ResolveError> where
T: ResolveOwned, [src]
T: ResolveOwned,
Resolve the given item into an owned variant.
pub fn eval<T>(
&self,
target: &T
) -> Result<<T::Output as IrEval>::Output, IrError> where
T: Spanned + IrCompile,
T::Output: IrEval, [src]
&self,
target: &T
) -> Result<<T::Output as IrEval>::Output, IrError> where
T: Spanned + IrCompile,
T::Output: IrEval,
Evaluate the given ast as a constant expression.
pub fn stringify<'a, T>(&'a self, tokens: &T) -> Stringify<'_> where
T: ToTokens, [src]
T: ToTokens,
Stringify the given token stream.
pub fn macro_span(&self) -> Span[src]
Access span of the whole macro.
pub fn stream_span(&self) -> Span[src]
Access the span of the stream being parsed.
pub fn storage(&self) -> &Storage[src]
Access storage for the macro system.
pub fn source(&self) -> &Source[src]
Access the current source of the macro context.
