Struct GraphContract 

pub struct GraphContract {
    pub vertex_types: BTreeMap<String, GraphVertexContract>,
    pub edge_types: BTreeMap<String, GraphEdgeContract>,
}

Implementations

impl GraphContract

pub fn from_json(json: &str) -> Result<GraphContract, ContractError>

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

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

pub fn validate_entities( &self, entities: &[&UnifiedEntity], ) -> Result<(), ContractError>

Validate a projected graph, after applying every change in a statement or merge. Additional properties are allowed; declared properties have exact native types and required properties cannot be absent or NULL.
