Struct ProjectionLayout 

pub struct ProjectionLayout {
    pub entries: Vec<(ProjectionId, usize)>,
    pub stride: usize,
}

A frozen memory layout: which projections are active, at what offsets.

Fields

entries: Vec<(ProjectionId, usize)>

Active projections with their byte offsets, in order.

stride: usize

Total bytes per atom (sum of all projection byte sizes).

Implementations

impl ProjectionLayout

pub fn from_projections(ids: &[ProjectionId]) -> Self

Create a layout from a set of projection IDs. Order is canonical (Splat, Kuramoto, Expert, Graph) regardless of input order.

pub fn full() -> Self

Full 5-projection layout (void instantiation — all projections present).

pub fn minimal() -> Self

Minimal layout: only Kuramoto + Splat (e.g., landing page).

pub fn offset_of(&self, id: ProjectionId) -> Option<usize>

Get byte offset for a projection, or None if not in layout.

pub fn has(&self, id: ProjectionId) -> bool

Whether a projection is active in this layout.

pub fn count(&self) -> usize

Number of active projections.

Trait Implementations

impl Clone for ProjectionLayout

fn clone(&self) -> ProjectionLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionLayout

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

Formats the value using the given formatter.
