Struct rustc_target::abi::TyLayout

pub struct TyLayout<'a, Ty> {
    pub ty: Ty,
    pub details: &'a LayoutDetails,
}

The details of the layout of a type, alongside the type itself. Provides various type traversal APIs (e.g. recursing into fields).

Note that the details are NOT guaranteed to always be identical to those obtained from layout_of(ty), as we need to produce layouts for which Rust types do not exist, such as enum variants or synthetic fields of enums (i.e. discriminants) and fat pointers.

Fields

ty: Ty

details: &'a LayoutDetails

Methods

impl<'a, Ty> TyLayout<'a, Ty>

pub fn for_variant<C>(self, cx: C, variant_index: usize) -> Self where     Ty: TyLayoutMethods<'a, C>,     C: LayoutOf<Ty = Ty>,

pub fn field<C>(self, cx: C, i: usize) -> C::TyLayout where     Ty: TyLayoutMethods<'a, C>,     C: LayoutOf<Ty = Ty>,

impl<'a, Ty> TyLayout<'a, Ty>

pub fn is_unsized(&self) -> bool

Returns true if the layout corresponds to an unsized type.

pub fn is_zst(&self) -> bool

Returns true if the type is a ZST and not unsized.

pub fn size_and_align(&self) -> (Size, Align)
