Fields

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<usize>

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.

Implementations

impl CodegenFnAttrs[src]

pub fn new() -> CodegenFnAttrs[src]

pub fn requests_inline(&self) -> bool[src]

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

pub fn contains_extern_indicator(&self) -> bool[src]

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
