Struct ProductTypeLayout

pub struct ProductTypeLayout {
    pub layout: Layout,
    pub elements: Box<[ProductTypeElementLayout]>,
}

A mirror of ProductType annotated with a Layout.

Fields

layout: Layout

The memoized layout of the product type.

elements: Box<[ProductTypeElementLayout]>

The fields of the product type with their own layout annotations.

Implementations

impl ProductTypeLayout

pub fn view(&self) -> ProductTypeLayoutView<'_>

Returns a view of this row type as a product type.

Trait Implementations

impl Clone for ProductTypeLayout

fn clone(&self) -> ProductTypeLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProductTypeLayout

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

Formats the value using the given formatter.

impl From<ProductType> for ProductTypeLayout

fn from(ty: ProductType) -> Self

Converts to this type from the input type.

impl HasLayout for ProductTypeLayout

fn layout(&self) -> &Layout

Returns the layout for objects of this type.

fn size(&self) -> usize

Returns the size, in bytes, for objects of this type.

fn align(&self) -> usize

Returns the alignment, in bytes, for objects of this type.

impl MemoryUsage for ProductTypeLayout

fn heap_usage(&self) -> usize

The heap memory usage of this type. The default implementation returns 0.

impl PartialEq for ProductTypeLayout

fn eq(&self, other: &ProductTypeLayout) -> 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.
