Enum IndexOutputKind 

#[non_exhaustive]
pub enum IndexOutputKind {
    U32,
    I32,
    I64,
}

Runtime tag for an IndexOutputElement. i64 is the default (PyTorch convention) and the only variant prior to Phase 12.2; u32 and i32 were added so downstream frameworks that prefer narrower index dtypes (Fuel uses u32) can avoid a post-pass cast.

#[non_exhaustive] — additional output index dtypes (u64 for frameworks that prefer unsigned indices end-to-end) may land in future phases. Match arms must include a _ => catch-all.

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.

U32

Unsigned 32-bit output index dtype.

I32

Signed 32-bit output index dtype.

I64

Signed 64-bit output index dtype — PyTorch default.

Trait Implementations

impl Clone for IndexOutputKind

fn clone(&self) -> IndexOutputKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IndexOutputKind

impl Debug for IndexOutputKind

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

Formats the value using the given formatter.

impl Eq for IndexOutputKind

impl Hash for IndexOutputKind

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

where __H: Hasher,

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 IndexOutputKind

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