Support for uploading data to the Taskcluster object server.
This crate provides a set of functions to perform an object-service upload. These functions negotiate an upload method with the object service, and then perform the upload, following all of the Taskcluster recommended practices.
Each function takes the necessary metadata for the upload, a handle to the data to be uploaded, and a taskcluster::Object client. The data to be uploaded can come in a variety of forms, described below. The client must be configured with the necessary credentials to access the object service.
An upload may be retried, in which case the upload function must have access to the object data from the beginning.
This is accomplished with the
AsyncReaderFactory trait, which defines a
get_reader method to generate a fresh tokio::io::AsyncRead for each attempt.
Users for whom the supplied convenience functions are inadequate can add their own implementation of this trait.
Upload an object from an in-memory buffer.
Upload an object from a File. The file must be open in read mode and must be clone-able (that is, File::try_clone() must succeed) in order to support retried uploads.
Upload an object using an AsyncReaderFactory. This is useful for advanced cases where one of the convenience functions is not adequate.
