Macros§

define_helper 🔒
define_print 🔒
define_print_and_forward_display 🔒
forward_display_to_print 🔒
with_crate_prefix: Adds the crate:: prefix to paths where appropriate.
with_forced_impl_filename_line: Force us to name impls with just the filename/line number. We normally try to use types. But at some points, notably while printing cycle errors, this can result in extra or suboptimal error output, so this variable disables that check.
with_forced_trimmed_paths
with_no_queries: Avoids running any queries during prints.
with_no_trimmed_paths: Prevent path trimming if it is turned on. Path trimming affects Display impl of various rustc types, for example std::vec::Vec would be trimmed to Vec, if no other Vec is found.
with_no_visible_paths: Prevent selection of visible paths. Display impl of DefId will prefer visible (public) reexports of types as paths.
with_no_visible_paths_if_doc_hidden: Prevent selection of visible paths if the paths are through a doc hidden path.
with_reduced_queries: Avoids running select queries during any prints that occur during the closure. This may alter the appearance of some types (e.g. forcing verbose printing for opaque types). This method is used during some queries (e.g. explicit_item_bounds for opaque types), to ensure that any debug printing that occurs during the query computation does not end up recursively calling the same query.
with_resolve_crate_name: Adds the crate name prefix to paths where appropriate. Unlike with_crate_prefix, this unconditionally uses tcx.crate_name instead of sometimes using crate:: for local items.
with_types_for_signature: Print types for the purposes of a signature suggestion.
with_types_for_suggestion: Print types for the purposes of a suggestion.

RegionFolder 🔒: Folds through bound vars and placeholders, naming them
RegionHighlightMode: The “region highlights” are used to control region printing during specific error messages. When a “region highlight” is enabled, it gives an alternate way to print specific regions. For now, we always print those regions using a number, so something like “'0”.
RtnModeHelper
TraitClausePrintModifiersAndPath
TraitClausePrintWithBoundConstness
TraitRefPrintOnlyTraitName: Wrapper type for ty::TraitRef which opts-in to pretty printing only the trait name. That is, it will print Trait instead of <T as Trait<U>>.
TraitRefPrintOnlyTraitPath: Wrapper type for ty::TraitRef which opts-in to pretty printing only the trait path. That is, it will print Trait<U> instead of <T as Trait<U>>.
TraitRefPrintSugared: Wrapper type for ty::TraitRef which opts-in to pretty printing only the trait path, and additionally tries to “sugar” Fn(...) trait bounds.
