Module rustc_middle::ty::layout

Structs

• LayoutCx

Enums

• FnAbiError
  Error produced by attempting to compute or adjust a FnAbi.
• FnAbiRequest
• LayoutError
• SizeSkeleton
  Type size “skeleton”, i.e., the only information determining a type’s size. While this is conservative, (aside from constant sizes, only pointers, newtypes thereof and null pointer optimized enums are allowed), it is enough to statically check common use cases of transmute.
• ValidityRequirement
  Used in check_validity_requirement to indicate the kind of initialization that is checked to be valid

Constants

• FAT_PTR_ADDR
  The first half of a fat pointer.
• FAT_PTR_EXTRA
  The second half of a fat pointer.
• MAX_SIMD_LANES
  The maximum supported number of lanes in a SIMD vector.

Traits

• FnAbiOf
  Blanket extension trait for contexts that can compute FnAbis.
• FnAbiOfHelpers
  Trait for contexts that want to be able to compute FnAbis. This automatically gives access to FnAbiOf, through a blanket impl.
• HasParamEnv
• HasTyCtxt
• IntegerExt
• LayoutOf
  Blanket extension trait for contexts that can compute layouts of types.
• LayoutOfHelpers
  Trait for contexts that want to be able to compute layouts of types. This automatically gives access to LayoutOf, through a blanket impl.
• MaybeResult
• PrimitiveExt

Functions

• fn_can_unwind
  Calculates whether a function’s ABI can unwind or not.
• mul_sorted_consts 🔒
  When creating the layout for types with abstract consts in their size (i.e. [usize; 4 * N]), to ensure that they have a canonical order and can be compared directly we combine all constants, and sort the other terms. This allows comparison of expressions of sizes, allowing for things like transmuting between types that depend on generic consts. This returns None if multiplication of constants overflows.
