Struct spacetimedb_table::layout::SumTypeLayout

pub struct SumTypeLayout {
    pub layout: Layout,
    pub variants: Box<[SumTypeVariantLayout]>,
    pub tag_offset: u16,
}

A mirrior of SumType annotated with a Layout.

Fields

layout: Layout

The layout of a sum value of this sum type.

variants: Box<[SumTypeVariantLayout]>

The variants of the sum type.

tag_offset: u16

The relative offset of a sum value’s tag for sums of this type.

Implementations

impl SumTypeLayout

pub fn offset_of_variant_data(&self, _variant_tag: u8) -> usize

pub fn offset_of_tag(&self) -> usize

Trait Implementations

impl Debug for SumTypeLayout

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

Formats the value using the given formatter.

impl From<SumType> for SumTypeLayout

fn from(ty: SumType) -> Self

Converts to this type from the input type.

impl HasLayout for SumTypeLayout

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 SumTypeLayout

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