Struct GraphArtifact 

pub struct GraphArtifact {
    pub schema: String,
    pub tree: Option<String>,
    pub facts: FactSet,
}

A self-describing snapshot of an assembled graph.

Fields

schema: String

Schema tag (ARTIFACT_SCHEMA).

tree: Option<String>

Hex id of the HEAD tree this graph was assembled from, if recorded.

facts: FactSet

The full node/edge set.

Implementations

impl GraphArtifact

pub fn from_store(store: &Store) -> Result<Self, StoreError>

Capture the current contents of store as an artifact.

Errors

Returns StoreError if the store cannot be read.

pub fn to_json(&self) -> Result<String, StoreError>

Serialise to pretty, deterministic JSON.

Errors

Returns StoreError::Json if serialisation fails.

pub fn from_json(json: &str) -> Result<Self, StoreError>

Parse an artifact from JSON.

Errors

Returns StoreError::Json on malformed JSON, or StoreError::Corrupt if the schema tag is unrecognised.

pub fn load_into(&self, store: &mut Store) -> Result<(), StoreError>

Load this artifact into store, replacing its entire contents. If the artifact carries a tree id it is recorded, so a sync at the matching commit sees the graph as already applied; a tree-less artifact records no synced state.

Errors

Returns StoreError if the rebuild fails.
