Struct abi_stable::type_layout::TypeLayoutRange

#[repr(C)]
pub struct TypeLayoutRange { /* private fields */ }

A range of indices into a slice of type layouts which can store up to five indices inline, requiring additional layouts to be stored contiguously after the fourth one in the slice.

Implementations

impl TypeLayoutRange

pub const EMPTY: Self = _

An empty TypeLayoutRange.

pub const STORED_INLINE: usize = 5usize

How many indices can be stored inline.

pub const fn with_up_to_5(len: usize, indices: [u16; 5]) -> Self

Constructs a TypeLayoutRange with up to five type layout indices.

pub const fn with_more_than_5(len: usize, indices: [u16; 5]) -> Self

Constructs a TypeLayoutRange with more than five type layout indices, in which the indices from indices[4] onwards are stored contiguously in the slice.

pub const fn from_u64(bits: u64) -> Self

Constructs this TypeLayoutRange from its representation.

pub const fn to_u64(&self) -> u64

Converts this TypeLayoutRange into its representation.

pub const fn len(&self) -> usize

The amount of type layouts in this range.

pub const fn is_empty(&self) -> bool

Whether this range of type layouts is empty.

impl TypeLayoutRange

pub fn expand<'a>( &self, type_layouts: &'a [extern "C" fn() -> &'static TypeLayout], ) -> MultipleTypeLayouts<'a>

Expands this TypeLayoutRange into a MultipleTypeLayouts<'a>.

Trait Implementations

impl Clone for TypeLayoutRange

fn clone(&self) -> TypeLayoutRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeLayoutRange

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

Formats the value using the given formatter.

impl GetStaticEquivalent_ for TypeLayoutRange

type StaticEquivalent = _static_TypeLayoutRange

The 'static equivalent of Self

impl Ord for TypeLayoutRange

fn cmp(&self, other: &TypeLayoutRange) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TypeLayoutRange

fn eq(&self, other: &TypeLayoutRange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TypeLayoutRange

fn partial_cmp(&self, other: &TypeLayoutRange) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StableAbi for TypeLayoutRange

type IsNonZeroType = False

Whether this type has a single invalid bit-pattern.

const LAYOUT: &'static TypeLayout = _

The layout of the type provided by implementors.

const ABI_CONSTS: AbiConsts = _

const-equivalents of the associated types.
