Enum UploadSessionMode 

pub enum UploadSessionMode {
    ServiceProxied {
        staging: ProxiedStaging,
    },
    DirectPut {
        checksum_algorithm: ChecksumAlgorithm,
    },
    DirectMultipart {
        provider_upload_id: String,
        part_size_bytes: NonZeroU64,
        checksum_algorithm: ChecksumAlgorithm,
    },
}

Upload mode and its mode-specific state. The mode never changes.

Variants

ServiceProxied

The service receives the bytes and writes the content object itself, so it learns size and digest from the bytes as they pass.

Fields

staging: ProxiedStaging

Exclusive staging progress, which applies only to this mode.

DirectPut

The client writes the whole object through one presigned request.

Fields

checksum_algorithm: ChecksumAlgorithm

Checksum algorithm chosen when the session began.

DirectMultipart

The client uploads parts and the provider assembles the object.

Multipart sessions do not store a content reference at creation because one-pass and streaming clients may not know the final size or checksum. The client supplies those values at completion, when LoonFS verifies the assembled object.

Fields

provider_upload_id: String

The provider-side upload the parts assemble through, and the only provider handle LoonFS keeps: parts are the client’s bookkeeping, exactly as they are in the provider’s own API, so there is no durable record per part.

part_size_bytes: NonZeroU64

Byte length of every part except the last, settled at begin.

A session resumed after a lost begin response reads its geometry from here rather than being told a second, possibly different, one. Zero is not a geometry, so it is not representable.

checksum_algorithm: ChecksumAlgorithm

Checksum algorithm chosen when the session began. Part signing and completion continue to use it after a restart.
