Implementations§

source§

impl ModuleItems

source

pub fn free_items(&self) -> impl Iterator<Item = ItemId> + '_

Returns all non-associated locally defined items in all modules.

Note that this does not include associated items of impl blocks! It also does not include foreign items. If you want to e.g. get all functions, use definitions() below.

However, this does include the impl blocks themselves.

source

pub fn trait_items(&self) -> impl Iterator<Item = TraitItemId> + '_

source

pub fn impl_items(&self) -> impl Iterator<Item = ImplItemId> + '_

Returns all items that are associated with some impl block (both inherent and trait impl blocks).

source

pub fn foreign_items(&self) -> impl Iterator<Item = ForeignItemId> + '_

source

pub fn owners(&self) -> impl Iterator<Item = OwnerId> + '_

source

pub fn definitions(&self) -> impl Iterator<Item = LocalDefId> + '_

source

pub fn par_items( &self, f: impl Fn(ItemId) -> Result<(), ErrorGuaranteed> + DynSend + DynSync ) -> Result<(), ErrorGuaranteed>

source

pub fn par_trait_items( &self, f: impl Fn(TraitItemId) -> Result<(), ErrorGuaranteed> + DynSend + DynSync ) -> Result<(), ErrorGuaranteed>

source

pub fn par_impl_items( &self, f: impl Fn(ImplItemId) -> Result<(), ErrorGuaranteed> + DynSend + DynSync ) -> Result<(), ErrorGuaranteed>

source

pub fn par_foreign_items( &self, f: impl Fn(ForeignItemId) -> Result<(), ErrorGuaranteed> + DynSend + DynSync ) -> Result<(), ErrorGuaranteed>

impl<Tcx, T> DepNodeParams<Tcx> for T
where Tcx: DepContext, T: for<'a> HashStable<StableHashingContext<'a>> + Debug,

source§

default fn fingerprint_style() -> FingerprintStyle

source§

default fn to_fingerprint(&self, tcx: Tcx) -> Fingerprint

This method turns the parameters of a DepNodeConstructor into an opaque Fingerprint to be used in DepNode. Not all DepNodeParams support being turned into a Fingerprint (they don’t need to if the corresponding DepNode is anonymous).
source§

default fn to_debug_str(&self, _: Tcx) -> String

source§

default fn recover(_: Tcx, _: &DepNode) -> Option<T>

This method tries to recover the query key from the given DepNode, something which is needed when forcing DepNodes during red-green evaluation. The query system will only call this method if fingerprint_style() is not FingerprintStyle::Opaque. It is always valid to return None here, in which case incremental compilation will treat the query as having changed instead of forcing it.
