Shared mutable state used in Context and elsewhere.

Fields

tcx: TyCtxt<'tcx>

src_root: PathBuf

The path to the crate root source minus the file name. Used for simplifying paths to the highlighted source code files.

layout: Layout

This describes the layout of each page, and is not modified after creation of the context (contains info like the favicon and added html).

local_sources: FxHashMap<PathBuf, String>

The local file sources we’ve emitted and their respective url-paths.

show_type_layout: bool

Show the memory layout of types in the docs.

issue_tracker_base_url: Option<String>

The base-URL of the issue tracker for when an item has been tagged with an issue number.

created_dirs: RefCell<FxHashSet<PathBuf>>

The directories that have already been created in this doc run. Used to reduce the number of spurious create_dir_all calls.

module_sorting: ModuleSorting

This flag indicates whether listings of modules (in the side bar and documentation itself) should be ordered alphabetically or in order of appearance (in the source code).

style_files: Vec<StylePath>

Additional CSS files to be added to the generated docs.

resource_suffix: String

Suffix to add on resource files (if suffix is “-v2” then “search-index.js” becomes “search-index-v2.js”).

static_root_path: Option<String>

Optional path string to be used to load static files on output pages. If not set, uses combinations of ../ to reach the documentation root.

fs: DocFS

The fs handle we are working with.

codes: ErrorCodes

playground: Option<Playground>

all: RefCell<AllTypes>

errors: Receiver<String>

Storage for the errors produced while generating documentation so they can be printed together at the end.

redirections: Option<RefCell<FxHashMap<String, String>>>

None by default, depends on the generate-redirect-map option flag. If this field is set to Some(...), it’ll store redirections and then generate a JSON file at the top level of the crate.

span_correspondence_map: FxHashMap<Span, LinkFromSrc>

Correspondence map used to link types used in the source code pages to allow to click on links to jump to the type’s definition.

cache: Cache

The Cache used during rendering.

call_locations: FxHashMap<DefPathHash, FxHashMap<PathBuf, CallData>>

Implementations

impl SharedContext<'_>

pub(crate) fn ensure_dir(&self, dst: &Path) -> Result<(), Error>

pub(crate) fn edition(&self) -> Edition

pub(crate) fn all_impls_for_item<'a>( &'a self, it: &Item, did: DefId ) -> Vec<&'a Impl>

Returns a list of impls on the given type, and, if it’s a type alias, other types that it aliases.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
