Struct rustc_target::abi::call::ArgAttributes

pub struct ArgAttributes {
    pub regular: ArgAttribute,
    pub arg_ext: ArgExtension,
    pub pointee_size: Size,
    pub pointee_align: Option<Align>,
}

A compact representation of LLVM attributes (at least those relevant for this module) that can be manipulated without interacting with LLVM’s Attribute machinery.

Fields

regular: ArgAttribute

arg_ext: ArgExtension

pointee_size: Size

The minimum size of the pointee, guaranteed to be valid for the duration of the whole call (corresponding to LLVM’s dereferenceable and dereferenceable_or_null attributes).

pointee_align: Option<Align>

Implementations

impl ArgAttributes

pub fn new() -> Self

pub fn ext(&mut self, ext: ArgExtension) -> &mut Self

pub fn set(&mut self, attr: ArgAttribute) -> &mut Self

pub fn contains(&self, attr: ArgAttribute) -> bool

Trait Implementations

impl Clone for ArgAttributes

fn clone(&self) -> ArgAttributes

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArgAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ArgAttributes

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for ArgAttributeswhere
    __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq<ArgAttributes> for ArgAttributes

fn eq(&self, other: &ArgAttributes) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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.
