Documentation

Overview

Package storeresolver resolves compute refs against the chassis content-addressed artifact.Store (the same store snapshots use). A compute artifact lives at ref "computes/<alg>/<digest>": the data blob is the wasm module, the manifest blob is small JSON naming the engine. This keeps compute bytes out of the ops/stack_files tables and reuses the store that is already wired into the chassis.

Types

type Manifest

type Manifest struct {
	Engine string `json:"engine"`
	Alg    string `json:"alg,omitempty"`
	Digest string `json:"digest,omitempty"`
}

Manifest is the small JSON blob stored alongside the wasm; it records which engine runs the artifact.

type Resolver

type Resolver struct {
	// contains filtered or unexported fields
}

Resolver implements compute.Resolver over an artifact.Store.

func New

func New(store artifact.Store) *Resolver

New builds a Resolver over the given store.

func (*Resolver) Resolve

func (r *Resolver) Resolve(ctx context.Context, ref compute.Ref) (compute.Artifact, error)

Resolve fetches the wasm + engine for a ref. ErrNotFound maps to compute.ErrNotFound so callers can distinguish "absent" from "broken".
