Struct MacroContext 

pub struct MacroContext<'a> { /* private fields */ }

Context provided to macro expanders for creating AST nodes.

This provides the necessary state for creating synthetic AST nodes during macro expansion, including ID allocation and error reporting.

Implementations

impl<'a> MacroContext<'a>

pub fn new( next_id_fn: &'a mut dyn FnMut() -> i64, store_macro_call_fn: Option<&'a mut dyn FnMut(i64, &Span, &SpannedExpr, &str, &[SpannedExpr])>, ) -> Self

Create a new macro context.

pub fn next_id(&mut self) -> i64

Allocate the next unique node ID.

pub fn add_error(&mut self, message: String, span: Span)

Add an error message.

pub fn take_errors(&mut self) -> Vec<(String, Span)>

Take accumulated errors.

pub fn store_macro_call( &mut self, call_id: i64, span: &Span, receiver: &SpannedExpr, method_name: &str, args: &[SpannedExpr], )

Store the original macro call expression for IDE features.
