Module rustc_interface::callbacks
source ยท Expand description
Throughout the compiler tree, there are several places which want to have
access to state or queries while being inside crates that are dependencies
of rustc_middle
. To facilitate this, we have the
rustc_data_structures::AtomicRef
type, which allows us to setup a global
static which can then be set in this file at program startup.
See SPAN_TRACK
for an example of how to set things up.
The functions in this file should fall back to the default set in their
origin crate when the TyCtxt
is not present in TLS.
Functionsยง
- def_
id_ ๐debug This is a callback fromrustc_hir
as it cannot access the implicit state inrustc_middle
otherwise. - This is a callback from
rustc_query_system
as it cannot access the implicit state inrustc_middle
otherwise. - This is a callback from
rustc_query_system
as it cannot access the implicit state inrustc_middle
otherwise. - Sets up the callbacks in prior crates which we want to refer to the TyCtxt in.
- track_
diagnostic ๐This is a callback fromrustc_errors
as it cannot access the implicit state inrustc_middle
otherwise. It is used when diagnostic messages are emitted and stores them in the current query, if there is one. - track_
