createLayerFromFs

createLayerFromFs(fs, parent, command?): Promise<Layer>

Defined in: packages/core/src/kernel/layer.ts:455

Build a Layer object from a frozen memoryFS.

Parameters

fs

FrozenMemoryFS

Frozen memoryFS holding the layer’s diff content.

parent

string | undefined

Parent layer id, or undefined for the base layer.

command?

string

Optional build command that produced this layer.

Returns

Promise<Layer>

A fully-populated Layer.

Remarks

Computes content hash and size in parallel, derives the chain-aware id via chainAwareId, and stamps created with Date.now(). The returned layer is ready to hand to LayerStore.put. Shared by the builder’s .run() path and container commit.

Example

import { createLayerFromFs, createLayerStore } from '@fishnet/core'

const store = createLayerStore()
const layer = await createLayerFromFs(frozenFs, undefined, 'echo base')
store.put(layer)
