Module rustc_expand::base

Macros

• make_MacEager 🔒
• make_stmts_default 🔒

Structs

• DeriveResolution
• DummyResult
  Fill-in macro expansion result, to allow compilation to continue after hitting errors.
• ExpansionData
• ExtCtxt
  One of these is made during expansion and incrementally updated as we go; when a macro expansion occurs, the resulting nodes have the backtrace() -> expn_data of their expansion context stored into their span.
• Indeterminate
  Error type that denotes indeterminacy.
• MacEager
  MacResult implementation for the common case where you’ve already built each form of AST that you might return.
• ModuleData
• SyntaxExtension
  A struct representing a macro definition in “lowered” form ready for expansion.

Enums

• Annotatable
• ExpandResult
  Result of an expansion that may need to be retried. Consider using this for non-MultiItemModifier expanders as well.
• SyntaxExtensionKind
  A syntax extension kind.

Traits

• AttrProcMacro
• BangProcMacro
• GlobDelegationExpander
• LintStoreExpand
• MacResult
  The result of a macro expansion. The return values of the various methods are spliced into the AST at the callsite of the macro.
• MultiItemModifier
• ResolverExpand
• TTMacroExpander
  Represents a thing that maps token trees to Macro Results

• pretty_printing_compatibility_hack 🔒
  If this item looks like a specific enums from rental, emit a fatal error. See #73345 and #83125 for more details. FIXME(#73933): Remove this eventually.
• resolve_path
