Trait Implementations§

Source§

impl<T: IStable> IStable for Struct<T>

Source§

const REPORT: &'static TypeReport

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

const ID: u64 = 6_717_366_535_720_309_027u64

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

type Size = <<T as IStable>::Size as IUnsigned>::NextMultipleOf<<T as IStable>::Align>

The size of the annotated type in bytes.
Source§

type Align = <T as IStable>::Align

The alignment of the annotated type in bytes.
Source§

type ForbiddenValues = <T as IStable>::ForbiddenValues

The values that the annotated type cannot occupy.
Source§

type UnusedBits = <<T as IStable>::UnusedBits as IBitMask>::BitOr<<<<<<T as IStable>::Size as IUnsigned>::NextMultipleOf<<T as IStable>::Align> as IUnsigned>::AbsSub<<T as IStable>::Size> as IUnsignedBase>::PaddingBitMask as IBitMask>::Shift<<T as IStable>::Size>>

The padding bits in the annotated types

Source§

fn align() -> usize

Returns the alignment of the type.
Source§
