The result of a macro expansion. The return values of the various methods are spliced into the AST at the callsite of the macro.

Provided methods

fn make_expr(self: Box<Self>) -> Option<P<Expr>>

Create an expression.

fn make_items(self: Box<Self>) -> Option<SmallVec<[P<Item>; 1]>>

Create zero or more items.

fn make_impl_items(self: Box<Self>) -> Option<SmallVec<[ImplItem; 1]>>

Create zero or more impl items.

fn make_trait_items(self: Box<Self>) -> Option<SmallVec<[TraitItem; 1]>>

Create zero or more trait items.

fn make_foreign_items(self: Box<Self>) -> Option<SmallVec<[ForeignItem; 1]>>

Create zero or more items in an extern {} block

fn make_pat(self: Box<Self>) -> Option<P<Pat>>

Create a pattern.

fn make_stmts(self: Box<Self>) -> Option<SmallVec<[Stmt; 1]>>

Create zero or more statements.

By default this attempts to create an expression statement, returning None if that fails.

fn make_ty(self: Box<Self>) -> Option<P<Ty>>
