Struct RootManifest 

pub struct RootManifest {
    pub root: Option<Cid>,
    pub config: Config,
    pub created_at_millis: Option<u64>,
    pub updated_at_millis: Option<u64>,
}

Durable named-root payload.

A root manifest stores the complete tree handle needed to reopen a named snapshot. The root CID alone is not enough because chunking and encoding config determine how the tree should be interpreted.

Fields

root: Option<Cid>

Root node CID, or None for the empty tree.

config: Config

Tree configuration associated with this root.

created_at_millis: Option<u64>

Optional Unix timestamp in milliseconds when this named root was created.

updated_at_millis: Option<u64>

Optional Unix timestamp in milliseconds when this named root was updated.

Implementations

impl RootManifest

pub fn new(root: Option<Cid>, config: Config) -> Self

Create a new manifest from a root CID and config.

pub fn with_timestamps_millis( self, created_at_millis: Option<u64>, updated_at_millis: Option<u64>, ) -> Self

Set optional creation and update timestamps in Unix milliseconds.

pub fn with_created_at_millis(self, created_at_millis: u64) -> Self

Set the creation timestamp in Unix milliseconds.

pub fn with_updated_at_millis(self, updated_at_millis: u64) -> Self

Set the update timestamp in Unix milliseconds.

pub fn from_tree_with_timestamps_millis( tree: &Tree, created_at_millis: Option<u64>, updated_at_millis: Option<u64>, ) -> Self

Create a manifest from a tree and timestamp metadata.

pub fn from_tree(tree: &Tree) -> Self

Create a manifest from an existing tree handle.

pub fn into_tree(self) -> Tree

Convert this manifest into a tree handle.

pub fn to_tree(&self) -> Tree

Convert this manifest into a cloned tree handle.

pub fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serialize this manifest to a versioned, deterministic binary payload.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Decode a manifest from bytes produced by RootManifest::to_bytes.
