Struct Flat 

pub struct Flat<const SHAPE: u32>;

The Topology of a graph with no deps: edges anywhere: zero-sized, every dep list is empty by type, and the topological order is declaration order. The walks a Supervisor runs over it fold to plain index loops, and the dependency cascades (activate, deactivate, restart) collapse to their seed sets.

Implementations

impl<const SHAPE: u32> Flat<SHAPE>

pub const fn new() -> Self

The (zero-sized) flat topology.

Trait Implementations

impl<const SHAPE: u32> Default for Flat<SHAPE>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: usize, const SHAPE: u32> Topology<N> for Flat<SHAPE>

const SHAPE: u32 = SHAPE

Structural-fact bits (see shape). An unset bit promises the structure is absent from the whole graph.

fn deps_of(&self, _i: u8) -> &'static [u8]

The dependency indices of slot i — what node i declared it needs spawned first. Spawn ordering, not runtime coupling: see the crate docs on what a deps: edge does and does not assert.

fn order_at(&self, k: usize) -> u8

Return the slot index at topological position k (0..N).
