Fields§

§flags: CodegenFnAttrFlags§inline: InlineAttr

Parsed representation of the #[inline] attribute

§optimize: OptimizeAttr

Parsed representation of the #[optimize] attribute

§export_name: Option<Symbol>

The #[export_name = "..."] attribute, indicating a custom symbol a function should be exported under

§link_name: Option<Symbol>

The #[link_name = "..."] attribute, indicating a custom symbol an imported function should be imported as. Note that export_name probably isn’t set when this is set, this is for foreign items while #[export_name] is for Rust-defined functions.

§link_ordinal: Option<u16>

The #[link_ordinal = "..."] attribute, indicating an ordinal an imported function has in the dynamic library. Note that this must not be set when link_name is set. This is for foreign items with the “raw-dylib” kind.

§target_features: Vec<Symbol>

The #[target_feature(enable = "...")] attribute and the enabled features (only enabled features are supported right now).

§linkage: Option<Linkage>

The #[linkage = "..."] attribute on Rust-defined items and the value we found.

§import_linkage: Option<Linkage>

The #[linkage = "..."] attribute on foreign items and the value we found.

§link_section: Option<Symbol>

The #[link_section = "..."] attribute, or what executable section this should be placed in.

§no_sanitize: SanitizerSet

The #[no_sanitize(...)] attribute. Indicates sanitizers for which instrumentation should be disabled inside the annotated function.

§instruction_set: Option<InstructionSetAttr>

The #[instruction_set(set)] attribute. Indicates if the generated code should be generated against a specific instruction set. Only usable on architectures which allow switching between multiple instruction sets.

§alignment: Option<Align>

The #[repr(align(...))] attribute. Indicates the value of which the function should be aligned to.

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.
