Struct ArrayLayout

pub struct ArrayLayout<T> { /* private fields */ }

A layout for an array [T; n].

Invariants

• len * size_of::<T>() <= isize::MAX.

Implementations

impl<T> ArrayLayout<T>

pub const fn empty() -> Self

Creates a new layout for [T; 0].

pub const fn new(len: usize) -> Result<Self, LayoutError>

Creates a new layout for [T; len].

Errors

When len * size_of::<T>() overflows or when len * size_of::<T>() > isize::MAX.

pub unsafe fn new_unchecked(len: usize) -> Self

Creates a new layout for [T; len].

Safety

len must be a value, for which len * size_of::<T>() <= isize::MAX is true.

pub const fn len(&self) -> usize

Returns the number of array elements represented by this layout.

pub const fn is_empty(&self) -> bool

Returns true when no array elements are represented by this layout.

Trait Implementations

impl<T> Clone for ArrayLayout<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> From<ArrayLayout<T>> for Layout

fn from(value: ArrayLayout<T>) -> Self

Converts to this type from the input type.
