Crate nuts_directory

Nuts backend implementation where the blocks of the container are stored in a file hierarchy.

Introduction

The nuts-directory crate implements a nuts backend where the blocks of the container are stored in a file hierarchy. Each block is identified by an id, which is basically a 16 byte random number.

When storing a block to disks the path to the file is derived from the id:

1. The id is converted into a hex string.
2. The path then would be: <first two chars>/<next two chars>/<remaining chars>

The header of the container is stored in the file 00/00/0000000000000000000000000000.

Create a new backend instance

The CreateOptions type is used to create a new backend instance, which is passed to the Container::create method. You need at least a directory where the backend put its blocks. See the CreateOptions documentation for further options.

Open an existing backend

The OpenOptions type is used to open a backend instance, which is passed to the Container::open method. You need the directory where the backend put its blocks.
