Struct EncodeAtomDevice 

pub struct EncodeAtomDevice {
    pub d: usize,
    pub m: usize,
    pub p: usize,
    pub topk: usize,
    pub newton_steps: usize,
    pub ridge: f64,
    pub exponents: Vec<i32>,
    pub decoder: Vec<f64>,
    pub charts: Vec<EncodeChartDevice>,
}

One EuclideanPatch atom’s frozen encode data, flattened for a device launch. This is exactly what the online encode reads: the monomial exponent table, the decoder B, and the offline-certified charts. Built from a real atom + its AtomEncodeAtlas by EncodeAtomDevice::from_atom_atlas so the device path consumes the identical data the CPU path does.

Fields

d: usize

Latent dimension d.

m: usize

Basis size m (number of monomials of total degree ≤ degree).

p: usize

Output dimension p.

topk: usize

Number of nearest charts refined per row (CERTIFIED_ROUTING_TOPK).

newton_steps: usize

Online Newton refinement steps after a certified landing.

ridge: f64

Levenberg ridge added to the per-row Hessian diagonal.

exponents: Vec<i32>

Monomial exponents, row-major exponents[col*d + axis], length m*d.

decoder: Vec<f64>

Decoder B, row-major decoder[basis*p + out], length m*p.

charts: Vec<EncodeChartDevice>

Charts (routing + warm-start + certificate constants).

Implementations

impl EncodeAtomDevice

pub fn from_atom_atlas( atom: &SaeManifoldAtom, atom_atlas: &AtomEncodeAtlas, config: &AtlasConfig, ) -> Result<Self, String>

Extract the device encode data from a real EuclideanPatch atom and its offline atlas. Recomputes the monomial exponent table (the atom’s own basis design) so the on-device evaluation is the SAME polynomial the host EuclideanPatchEvaluator evaluates.

Trait Implementations

impl Clone for EncodeAtomDevice

fn clone(&self) -> EncodeAtomDevice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EncodeAtomDevice

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

Formats the value using the given formatter.
