Structs§
- Derive
Resolution - Dummy
Result - Fill-in macro expansion result, to allow compilation to continue after hitting errors.
- Expansion
Data - 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_dataof their expansion context stored into their span. - Indeterminate
- Error type that denotes indeterminacy.
- MacEager
MacResultimplementation for the common case where you’ve already built each form of AST that you might return.- Module
Data - Syntax
Extension - A struct representing a macro definition in “lowered” form ready for expansion.
Enums§
- Annotatable
- This type encapsulates every AST node that can have attributes, i.e. those
nodes with a non-trivial implementation of
HasAttrs. - Expand
Result - Result of an expansion that may need to be retried.
Consider using this for non-
MultiItemModifierexpanders as well. - Syntax
Extension Kind - A syntax extension kind.
Traits§
- Attr
Proc Macro - Bang
Proc Macro - Glob
Delegation Expander - Lint
Store Expand - 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.
- Multi
Item Modifier - Resolver
Expand - TTMacro
Expander - Represents a thing that maps token trees to Macro Results
