Struct ContentRef 

pub struct ContentRef {
    pub kind: ContentRefKind,
    pub owner_namespace_id: NamespaceId,
    pub content_id: ContentId,
    pub size_bytes: u64,
    pub checksum: Checksum,
}

A reference to one immutable content object.

The object must be durable before the reference is published.

Fields

kind: ContentRefKind

Content strategy used by the referenced object.

owner_namespace_id: NamespaceId

Namespace that originally wrote the bytes.

content_id: ContentId

Immutable identity of the referenced object.

size_bytes: u64

Complete byte length of the referenced content.

checksum: Checksum

Mandatory checksum over the complete object.

Implementations

impl ContentRef

pub fn blob_v1( owner_namespace_id: NamespaceId, content_id: ContentId, bytes: &[u8], ) -> Self

Builds a reference to a freshly minted content object holding these bytes.

Every caller of this constructor moves the bytes through the LoonFS write path, so the checksum is trusted by construction.

pub fn blob_v1_streamed( owner_namespace_id: NamespaceId, content_id: ContentId, size_bytes: u64, digest: Sha256, ) -> Self

Builds a content reference from a SHA-256 computed while streaming the payload.

Accepting the digest object, rather than an arbitrary checksum string, ensures that the checksum came from the LoonFS write path.

pub fn validate(&self) -> Result<(), ContentRefValidationError>

Reports whether the reference is well formed enough to publish.

This is a shape check on the reference itself; proving that the object exists and matches is the storage layer’s job.
