Struct spacetimedb_table::layout::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 algebraic_type(&self) -> AlgebraicType

Convert a ProductTypeLayout back into an AlgebraicType::Product, removing layout information.

This operation is O(n) in the number of nodes in the argument, and will heap-allocate. It is intended for use in error paths, where performance is a secondary concern.

impl ProductTypeLayout

pub fn offset_of_element(&self, field_idx: usize) -> usize

Returns the offset of the element at field_idx.

Trait Implementations

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 From<ProductTypeLayout> for RowTypeLayout

fn from(cols: ProductTypeLayout) -> 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 PartialEq for ProductTypeLayout

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