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.

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

something which is needed when forcing DepNode
s 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 moresource§impl<T, R> InternIteratorElement<T, R> for T

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.
