Trait MultipartUploadJournal 

pub trait MultipartUploadJournal: Send + Sync {
    // Required methods
    fn began(&self, upload_id: &UploadId, part_size_bytes: u64);
    fn part_completed(&self, part: &CompletedUploadPart);
}

Where a caller records a direct multipart upload as it happens, so a later run can resume it.

Both methods are called on the thread driving the upload, between network round trips, so an implementation that writes to disk is doing it at the right moment: after the part it describes is durable, and before the next one starts.

Required Methods

fn began(&self, upload_id: &UploadId, part_size_bytes: u64)

A session was opened, with the part geometry the server chose.

fn part_completed(&self, part: &CompletedUploadPart)

One part landed in object storage.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
