Struct rustc_target::abi::call::ArgAbi

pub struct ArgAbi<'a, Ty> {
    pub layout: TyAndLayout<'a, Ty>,
    pub mode: PassMode,
}

Information about how to pass an argument to, or return a value from, a function, under some ABI.

Fields

layout: TyAndLayout<'a, Ty>

mode: PassMode

Implementations

impl<'a, Ty> ArgAbi<'a, Ty>

pub fn new( cx: &impl HasDataLayout, layout: TyAndLayout<'a, Ty>, scalar_attrs: impl Fn(&TyAndLayout<'a, Ty>, Scalar, Size) -> ArgAttributes ) -> Self

This defines the “default ABI” for that type, that is then later adjusted in fn_abi_adjust_for_abi.

fn indirect_pass_mode(layout: &TyAndLayout<'a, Ty>) -> PassMode

pub fn make_direct_deprecated(&mut self)

Pass this argument directly instead. Should NOT be used! Only exists because of past ABI mistakes that will take time to fix (see https://github.com/rust-lang/rust/issues/115666).

pub fn make_indirect(&mut self)

pub fn make_indirect_byval(&mut self, byval_align: Option<Align>)

pub fn extend_integer_width_to(&mut self, bits: u64)

pub fn cast_to<T: Into<CastTarget>>(&mut self, target: T)

pub fn cast_to_and_pad_i32<T: Into<CastTarget>>( &mut self, target: T, pad_i32: bool )

pub fn is_indirect(&self) -> bool

pub fn is_sized_indirect(&self) -> bool

pub fn is_unsized_indirect(&self) -> bool

pub fn is_ignore(&self) -> bool

pub fn eq_abi(&self, other: &Self) -> bool

Checks if these two ArgAbi are equal enough to be considered “the same for all function call ABIs”.

Trait Implementations

impl<'a, Ty: Clone> Clone for ArgAbi<'a, Ty>

fn clone(&self) -> ArgAbi<'a, Ty>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, Ty: Display> Debug for ArgAbi<'a, Ty>

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

Formats the value using the given formatter.

impl<'a, Ty: Hash> Hash for ArgAbi<'a, Ty>

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<'a, Ty, __CTX> HashStable<__CTX> for ArgAbi<'a, Ty>

where __CTX: HashStableContext, Ty: HashStable<__CTX>,

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

impl<'a, Ty: PartialEq> PartialEq for ArgAbi<'a, Ty>

fn eq(&self, other: &ArgAbi<'a, Ty>) -> 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.

impl<'a, Ty: Eq> Eq for ArgAbi<'a, Ty>

impl<'a, Ty> StructuralPartialEq for ArgAbi<'a, Ty>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
