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<u32>

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

Implementations§

impl CodegenFnAttrs

source

pub const EMPTY: &'static Self = _

source

pub const fn new() -> CodegenFnAttrs

source

pub fn requests_inline(&self) -> bool

Returns true if #[inline] or #[inline(always)] is present.

source

pub fn contains_extern_indicator(&self) -> bool

Returns true if it looks like this symbol needs to be exported, for example:

impl<T, R> CollectAndApply<T, R> for T

source§

fn collect_and_apply<I, F>(iter: I, f: F) -> Rwhere I: Iterator<Item = T>, F: FnOnce(&[T]) -> R,

source§

impl<Tcx, T> DepNodeParams<Tcx> for Twhere 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.

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.
