Constructor Details

#initialize(fetcher) ⇒ BlobList

You should not instanciate this object directly, but obtain one when calling relevant methods of AzureBlob::Client.

Expects a callable object that takes an Azure API page marker as an argument and returns the raw body response of a call to the list blob endpoint.

Example:

fetcher = ->(marker) do
  uri.query = URI.encode_www_form(
    marker: marker,
    ...
  )
  response = Http.new(uri, signer:).get
end
AzureBlob::BlobList.new(fetcher)
