Struct PaddingHelper

#[repr(C)]
pub struct PaddingHelper<Double: IStable<Align = U1>, Bit: IBitBase>(/* private fields */);

A helper to generate padding of appropriate size.

Trait Implementations

impl<Double: IStable<Align = U1> + Copy, Bit: IBitBase> Clone for PaddingHelper<Double, Bit>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Double: IStable<Align = U1> + Default, Bit: IBitBase> Default for PaddingHelper<Double, Bit>

fn default() -> Self

Returns the “default value” for a type.

impl<Double: IStable<Align = U1>, Bit: IBitBase> IStable for PaddingHelper<Double, Bit>

const REPORT: &'static TypeReport

A compile-time generated report of the fields of the type, allowing for compatibility inspection.

const ID: u64 = 12_375_681_673_216_407_606u64

A stable (and ideally unique) identifier for the type. Often generated using crate::report::gen_id, but can be manually set.

type Align = UInt<UTerm, B1>

The alignment of the annotated type in bytes.

type Size = <<UInt<UInt<UTerm, B1>, B0> as IUnsigned>::Mul<<Double as IStable>::Size> as IUnsigned>::Add<<Bit as IBitBase>::_UTernary<UInt<UTerm, B1>, UTerm>>

The size of the annotated type in bytes.

type ForbiddenValues = End

The values that the annotated type cannot occupy.

type ContainsIndirections = B0

Whether or not the type contains indirections (pointers, indices in independent data-structures…)

type HasExactlyOneNiche = B0

Allows the detection of whether or not core::option::Options are stable:

type UnusedBits = <Tuple3<Double, Double, <Bit as IBitBase>::_Padding> as IStable>::UnusedBits

The padding bits in the annotated types

fn size() -> usize

Returns the size of the type.

fn align() -> usize

Returns the alignment of the type.

unsafe fn is_invalid(ptr: *const u8) -> bool

Returns true if ptr points to memory that cannot be a valid value of Self.
