Module rustc_expand::expand
source · Macros
Wraps a call to
noop_visit_* / noop_flat_map_*
for an AST node that supports attributes
(see the Annotatable enum)
This method assigns a NodeId, and sets that NodeId
as our current ‘lint node id’. If a macro call is found
inside this AST node, we will use this AST node’s NodeId
to emit lints associated with that macro (allowing
#[allow] / #[deny] to be applied close to
the macro invocation).Structs
Enums
A fragment of AST that can be produced by a single macro expansion.
Can also serve as an input and intermediate result for macro expansion operations.
“Discriminant” of an AST fragment.
Traits
A trait implemented for all
AstFragment nodes and providing all pieces
of functionality used by InvocationCollector.
