Struct spirt::qptr::shapes::MemLayout

pub struct MemLayout {
    pub align: u32,
    pub legacy_align: u32,
    pub size: u32,
}

Untyped memory shape with constant alignment and size.

align/legacy_align correspond to “scalar”/“base” alignments in Vulkan, and are both kept track of to detect ambiguity in implicit layouts, e.g. field offsets when the Offset decoration isn’t being used. Note, however, that legacy_align can be raised to “extended” alignment, or completeley ignored, using LayoutConfig.

Only align is required, that is size % align == 0 must be always enforced.

Fields

align: u32

legacy_align: u32

size: u32

Trait Implementations

impl Clone for MemLayout

fn clone(&self) -> MemLayout

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemLayout

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

Formats the value using the given formatter.

impl Hash for MemLayout

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemLayout

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