source · Structs
This is the implicit state of rustc. It contains the current
TyCtxt
and query. It is updated when creating a local interner or
executing a new query. Whenever there’s a TyCtxt
value available
you should also have access to an ImplicitCtxt
through the functions
in this module.Functions

The closure is passed None if there is no ImplicitCtxt
available.Allows access to the current
ImplicitCtxt
whose tcx field is the same as the tcx argument
passed in. This means the closure is given an ImplicitCtxt
with the same 'tcx
lifetime
as the TyCtxt
passed in.
This will panic if you pass it a TyCtxt
which is different from the current
ImplicitCtxt
’s tcx
field.
