Struct rustc_target::abi::Layout

pub struct Layout<'a>(pub Interned<'a, LayoutS<FieldIdx, VariantIdx>>);

Tuple Fields

0: Interned<'a, LayoutS<FieldIdx, VariantIdx>>

Implementations

impl<'a> Layout<'a>

pub fn fields(self) -> &'a FieldsShape<FieldIdx>

pub fn variants(self) -> &'a Variants<FieldIdx, VariantIdx>

pub fn abi(self) -> Abi

pub fn largest_niche(self) -> Option<Niche>

pub fn align(self) -> AbiAndPrefAlign

pub fn size(self) -> Size

pub fn max_repr_align(self) -> Option<Align>

pub fn unadjusted_abi_align(self) -> Align

pub fn is_pointer_like(self, data_layout: &TargetDataLayout) -> bool

Whether the layout is from a type that implements std::marker::PointerLike.

Currently, that means that the type is pointer-sized, pointer-aligned, and has a scalar ABI.

Trait Implementations

impl<'a> Clone for Layout<'a>

fn clone(&self) -> Layout<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Layout<'a>

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

Formats the value using the given formatter.

impl<'a> Deref for Layout<'a>

type Target = &'a LayoutS<FieldIdx, VariantIdx>

The resulting type after dereferencing.

fn deref(&self) -> &&'a LayoutS<FieldIdx, VariantIdx>

Dereferences the value.

impl<'a> Hash for Layout<'a>

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, __CTX> HashStable<__CTX> for Layout<'a>where __CTX: HashStableContext,

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

impl<'a> PartialEq<Layout<'a>> for Layout<'a>

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