Enum ChecksumAlgorithm 

pub enum ChecksumAlgorithm {
    Sha256,
    Crc64nvme,
    Crc32c,
}

Algorithm of a stored full-object checksum.

Every algorithm here covers the complete object. There is deliberately no checksum-type field: full-object coverage is an invariant of this format, established when the object is written, never read back from a provider. (Cloudflare R2 never reports x-amz-checksum-type at all, so a type read back would be unavailable exactly where it would matter.)

ChecksumAlgorithm::Sha256 and ChecksumAlgorithm::Crc64nvme both have producers: every path that moves bytes through LoonFS hashes them, and direct multipart upload carries the CRC-64/NVME the S3-compatible providers compute over the assembled object. Crc32c decodes and round-trips without a producer.

Variants

Sha256

SHA-256 over the complete object.

Crc64nvme

CRC-64/NVME over the complete object.

Crc32c

CRC-32C over the complete object.
