flags: CodegenFnAttrFlagsinline: 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 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.


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

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

  • #[no_mangle] is present
  • #[export_name(...)] is present
  • #[linkage] is present

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). Read more

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. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
