Enum Operation 

#[non_exhaustive]
pub enum Operation {
    Identity,
    Zero,
    Conv3x3,
    Conv5x5,
    MaxPool,
    AvgPool,
    SkipConnect,
}

Candidate primitive operations for DARTS cells.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Identity

Identity (skip connection).

Zero

Zero (no information flow).

Conv3x3

3×3 separable convolution.

Conv5x5

5×5 separable convolution.

MaxPool

3×3 max pooling.

AvgPool

3×3 average pooling.

SkipConnect

Skip connection (same as Identity but conceptually distinct).

Implementations

impl Operation

pub fn cost_flops(&self, channels: usize) -> f64

Rough FLOP estimate for a single forward pass through this operation.

Formula used: conv FLOPs ≈ 2 * kernel² * channels² (assuming spatial size = 1 for simplicity; callers may scale by H*W).

pub fn name(&self) -> &'static str

Human-readable name used in diagnostic output.

pub fn all() -> &'static [Operation]

All primitive operations in a fixed canonical order.

Trait Implementations

impl Clone for Operation

fn clone(&self) -> Operation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operation

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

Formats the value using the given formatter.

impl Hash for Operation

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 Operation

fn eq(&self, other: &Operation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
