Struct EngineShim 

pub struct EngineShim<'a> {
    pub spec: &'a ModelSpec,
    pub numerics: EngineNumerics,
}

The engine’s shim for one model at one knob point: its spec says which checkpoint tensor and view each constant reads, its numerics the contract its build keeps — which change the contract, never what the engine runs whole.

Fields

spec: &'a ModelSpec

numerics: EngineNumerics

Trait Implementations

impl Shim for EngineShim<'_>

fn name(&self) -> String

The chip and the configuration it answers for, e.g. cuda-lane:rtx3060:TwoPassInt8.

fn supports(&self, class: ClassId) -> Support

What the chip’s link does with class. Every chip answers by a match over every class with no catch-all arm, so a class added to the registry fails the build until each chip answers it.

fn fits(&self, op: &Op, _: &TensorGraph) -> Result<(), String>

Whether the chip’s link builds op as it stands — its shapes, its accesses, its destination: Ok, or why not.

fn activation(&self, _: &Op, _: usize, _: &TensorGraph) -> Option<QuantFormat>

The quantized form consumer reads its operand operand in, or None for one it reads as its values.

fn numerics(&self) -> Option<Contract>

The numerics contract of the knob point the chip answers for, or None while the chip has not declared it.

fn rules(&self) -> Vec<(Position, ChipRule<'_>)>

The chip’s own rules, each linked into the table where its position says.
