Struct I4 

pub struct I4;

INT4: two signed 4-bit nibbles per byte. ONNX TensorProto.DataType = 22.

Trait Implementations

impl Clone for I4

fn clone(&self) -> I4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstrainedTypeShape for I4

const IRI: &'static str = "https://uor.foundation/type/ConstrainedType"

IRI of the ontology type:ConstrainedType instance this shape represents.

const SITE_COUNT: usize = PACKED_NIBBLE_BYTES

Number of sites (fields) this constrained type carries.

const CONSTRAINTS: &'static [ConstraintRef]

Per-site constraint list. Empty means unconstrained.

const CYCLE_SIZE: u64

ADR-032: cardinality of the shape’s value-set (the cycle structure of the shape under the substrate’s discrete-clock model). Used by the prism_model! macro to lower first_admit (closure-body grammar G16) to the correct descent measure. Conventions:

const SITE_BUDGET: usize = Self::SITE_COUNT

Ontology-level siteBudget: count of data sites only, excluding bookkeeping introduced by composition (coproduct tag sites, etc.). Equals SITE_COUNT for leaf shapes and for shapes whose composition introduces no bookkeeping (products, cartesian products). Strictly less than SITE_COUNT for coproduct shapes and any shape whose SITE_COUNT includes inherited bookkeeping. Introduced by the Product/Coproduct Completion Amendment §4a; defaults to SITE_COUNT so pre-amendment shape impls remain valid without edits.

impl Debug for I4

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

Formats the value using the given formatter.

impl Default for I4

fn default() -> I4

Returns the “default value” for a type.

impl Dtype for I4

const NAME: &'static str = "I4"

Per-dtype name string (uppercase, GGML-convention spelling).

const BLOCK_BYTES: usize = PACKED_NIBBLE_BYTES

Bytes per block. For continuous element types this is the element byte count; for quantized types this is the block-bytes count (= the GGML block_q*_* sizeof).

const BLOCK_ELEMS: usize = PACKED_NIBBLE_ELEMS

Elements per block. 1 for continuous types; 32 for legacy quantization; 256 for K-series quantization.

impl<'a> IntoBindingValue<'a> for I4

fn as_binding_value<const INLINE_BYTES: usize>( &self, ) -> TermValue<'a, INLINE_BYTES>

Return this input value’s canonical content-addressable bytes as a source-polymorphic crate::pipeline::TermValue carrier (ADR-060). Inline for values within the derived inline width, Borrowed for larger in-memory values (zero-copy), or Stream for unbounded sources. The carrier borrows the input’s 'a-lived data; for an Inline-only input it owns its bytes and is valid for any 'a.
