Enum TensorRole 

pub enum TensorRole {
    Input,
    Output,
    Param,
    Activation,
    State,
}

Variants

Input

Output

Param

Activation

Produced by one section of a program and consumed by a later one — stored AND loaded inside a single program, which Input and Output each forbid. It starts a run EMPTY, like an output: a section that reads it before its producer wrote it faults, which is what makes the section barrier load-bearing rather than decorative.

State

Carried ACROSS steps (the GDN memory, the conv ring, the KV cache): read at the start of a step and written once at its end. It starts a run FILLED, like an input, and leaves it in the outputs, so two steps of the same program chain through it.

Implementations

impl TensorRole

pub fn starts_filled(self) -> bool

Whether a run STARTS with this tensor’s data present. An activation does not: it is produced inside the run, so reading it early is a fault, not a stale value.

pub fn is_written(self) -> bool

Whether a Store may write this tensor.

pub fn is_read(self) -> bool

Whether a Load may read this tensor.

pub fn is_fully_covered(self) -> bool

Whether EVERY tile of this tensor must be written exactly once by the run. A state tensor is the one role that may be updated in part (a ring that shifts, a cache row that is appended), so it is held to “at most once” instead.

Trait Implementations

impl Clone for TensorRole

fn clone(&self) -> TensorRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TensorRole

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TensorRole

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TensorRole

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 TensorRole

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

impl Serialize for TensorRole

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
