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>>[src]

Creates an expression.

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

Creates zero or more items.

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

Creates zero or more impl items.

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

Creates zero or more trait items.

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

Creates zero or more items in an extern {} block

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

Creates a pattern.

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

Creates zero or more statements.

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

fn make_pat_fields(self: Box<Self>) -> Option<SmallVec<[PatField; 1]>>[src]

fn make_generic_params(self: Box<Self>) -> Option<SmallVec<[GenericParam; 1]>>[src]

fn make_params(self: Box<Self>) -> Option<SmallVec<[Param; 1]>>[src]

fn make_field_defs(self: Box<Self>) -> Option<SmallVec<[FieldDef; 1]>>[src]

fn make_variants(self: Box<Self>) -> Option<SmallVec<[Variant; 1]>>[src]
