FieldBindings | Represents the binding of a struct or enum variant's fields to a corresponding set of similarly named local variables. |

Functions
build_coprod_constr | Given an index and an expression or pattern, creates an AST for the corresponding Coproduct constructor, which may itself be used as an expression or a pattern. |
build_coprod_type | Given a list of types, creates an AST for the corresponding Coproduct type. |
build_coprod_unreachable_arm | Given the length of a Coproduct type, generates an "unreachable" match arm, matching the CNil case in order to work around limitations in the compiler's exhaustiveness checking. |
build_field_expr | |
build_field_pat | |
build_field_type | |
build_hlist_constr | Given a list of expressions or patterns, creates an AST for the corresponding HList constructor, which may itself be used as an expression or a pattern. |
build_hlist_type | Given a list of types, creates an AST for the corresponding HList type. |
build_label_type | Given an Ident returns an AST for its type level representation based on the enums generated in frunk_core::labelled. |
build_path_type | |
call_site_ident | Returns an Ident |
find_idents_in_expr | Returns the idents in a path like expression in reverse |
ref_generics | |
to_ast | Parses a TokenStream (usually received as input into a custom derive function), into a syn MacroInput AST, which is nice. |
