Create a new chunk store. Chunks must have a length of chunkLength.

Add a new chunk to the storage. Index should be an integer.

Retrieve a chunk stored. Index should be an integer. Options include:

{
  offset: chunkByteOffset,
  length: byteLength
}

If the index doesn't exist in the storage an error should be returned.

Close the underlying resource, e.g. if the store is backed by a file, this would close the file descriptor.

Destroy the file data, e.g. if the store is backed by a file, this would delete the file from the filesystem.

Publishing a test suite as a module lets multiple modules all ensure compatibility since they use the same test suite.

To use the test suite from this module you can require('abstract-chunk-store/tests').

An example of this can be found in the memory-chunk-store test suite.

To run the tests simply pass your test module (tap or tape or any other compatible modules are supported) and your store's constructor (or a setup function) in:

var tests = require('abstract-chunk-store/tests')
tests(require('tape'), require('your-custom-chunk-store'))
