Trait Implementations

impl FxfsBlobMetadataExt for BlobMetadata

fn read_from<S: HandleOwner>( blob_object: &StoreObjectHandle<S>, ) -> impl Future<Output = Result<Self, Error>> + Send

Reads the blob metadata from an attribute on blob_object. If the attribute doesn’t exist then it’s assumed to be BlobMetadata::empty().

fn write_to<S: HandleOwner>( &self, blob_object: &DataObjectHandle<S>, ) -> impl Future<Output = Result<(), Error>> + Send

Writes the metadata to the AttributeId::BLOB_METADATA attribute on blob_object. If the metadata is equal to BlobMetadata::empty() then the attribute isn’t written.

fn serialized_size(&self) -> Result<usize, Error>

Returns the size of the serialized metadata. If the metadata is equal to BlobMetadata::empty() then the metadata won’t get written, so 0 is returned.

fn into_merkle_verifier(self, root: Hash) -> Result<MerkleVerifier, Error>

Consumes the metadata and turns it into a MerkleVerifier.
