Small Cache

A wazero host module, ABI and guest SDK providing a small cache suitable for sharing data between concurrent WASI modules.

Host Module

First register the host module with the runtime

import (
    "github.com/tetratelabs/wazero"
    "github.com/tetratelabs/wazero/imports/wasi_snapshot_preview1"

    "github.com/pantopic/ext-small-cache/host-wazero"
)

func main() {
    ctx := context.Background()
    r := wazero.NewRuntimeWithConfig(ctx, wazero.NewRuntimeConfig())
    wasi_snapshot_preview1.MustInstantiate(ctx, r)

    module := wazero_small_cache.New()
    module.Register(ctx, r)

    // ...
}

Guest SDK (Go)

Then you can import the guest SDK into your WASI module to send messages from one WASI module to another.

package main

import (
    "github.com/pantopic/ext-small-cache/sdk-go"
)

const (
	SMALL_CACHE_TEST = iota
)

var c *small_cache.Local

func main() {
    c = small_cache.NewLocal(SMALL_CACHE_TEST)
}

//export test
func test() {
    n.Put([]byte(`a`), []byte(`1`))
    println(n.Get([]byte(`a`))) // 1
}

Roadmap

This project is in alpha. Breaking API changes should be expected until Beta.

• v0.0.x - Alpha
  • Stabilize API
• v0.x.x - Beta
  • Finalize API
  • Test in production
• v1.x.x - General Availability
  • Proven long term stability in production
