Struct stabby_abi::Tuple

#[repr(C)]
pub struct Tuple<A, B>(pub A, pub B);

An ABI-stable tuple.

Tuple Fields

0: A

1: B

Implementations

impl<A, B> Tuple<A, B>

pub const fn has_optimal_layout() -> bool

Returns true if the layout for Tuple is smaller or equal to that Rust would have generated for it.

Trait Implementations

impl<A: Clone, B: Clone> Clone for Tuple<A, B>

fn clone(&self) -> Tuple<A, B>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A: Debug, B: Debug> Debug for Tuple<A, B>

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

Formats the value using the given formatter.

impl<A: Default, B: Default> Default for Tuple<A, B>

fn default() -> Tuple<A, B>

Returns the “default value” for a type.

impl<A: Hash, B: Hash> Hash for Tuple<A, B>

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, B> IStable for Tuple<A, B>

where Struct<FieldPair<A, B>>: IStable, A: IStable, B: IStable,

type ForbiddenValues = <Struct<FieldPair<A, B>> as IStable>::ForbiddenValues

The values that the annotated type cannot occupy.

type UnusedBits = <Struct<FieldPair<A, B>> as IStable>::UnusedBits

The padding bits in the annotated types

type Size = <Struct<FieldPair<A, B>> as IStable>::Size

The size of the annotated type in bytes.

type Align = <Struct<FieldPair<A, B>> as IStable>::Align

The alignment of the annotated type in bytes.

type HasExactlyOneNiche = <Struct<FieldPair<A, B>> as IStable>::HasExactlyOneNiche

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

type ContainsIndirections = <Struct<FieldPair<A, B>> as IStable>::ContainsIndirections

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

const REPORT: &'static TypeReport = _

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

const ID: u64 = _

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

fn size() -> usize

Returns the size of the type.

fn align() -> usize

Returns the alignment of the type.

impl<A: PartialEq, B: PartialEq> PartialEq for Tuple<A, B>

fn eq(&self, other: &Tuple<A, B>) -> 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.
