Fields§

§tcx: TyCtxt<'tcx>§index: Rc<RefCell<FxHashMap<Id, Item>>>

Trait Implementations§

source§

impl<'tcx> Clone for JsonRenderer<'tcx>

source§

fn clone(&self) -> JsonRenderer<'tcx>

Returns a copy of the value. Read more
1.0.0 · source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more
source§

impl<'tcx> FormatRenderer<'tcx> for JsonRenderer<'tcx>

source§

fn item(&mut self, item: Item) -> Result<(), Error>

Inserts an item into the index. This should be used rather than directly calling insert on the hashmap because certain items (traits and types) need to have their mappings for trait implementations filled out before they’re inserted.

source§

fn descr() -> &'static str

Gives a description of the renderer. Used for performance profiling.
source§

const RUN_ON_MODULE: bool = false

Whether to call item recursively for modules Read more
source§

fn init( krate: Crate, options: RenderOptions, cache: Cache, tcx: TyCtxt<'tcx> ) -> Result<(Self, Crate), Error>

Sets up any state required for the renderer. When this is called the cache has already been populated.
source§

fn make_child_renderer(&self) -> Self

Make a new renderer to render a child of the item currently being rendered.
source§

fn mod_item_in(&mut self, _item: &Item) -> Result<(), Error>

Renders a module (should not handle recursing into children).
source§

fn after_krate(&mut self) -> Result<(), Error>

Post processing hook for cleanup and dumping output to files.
source§

fn cache(&self) -> &Cache

source§

fn mod_item_out(&mut self) -> Result<(), Error>

Runs after recursively rendering all sub-items of a module.
