Struct FactDependencyGraph 

pub struct FactDependencyGraph { /* private fields */ }

The exact fact-level dependency graph used to order schema operations.

Implementations

impl FactDependencyGraph

pub fn from_declared(declared: &DeclaredSchema) -> Result<Self, Diagnostic>

Build the graph from a complete declared fact inventory.

pub fn from_facts<'a>( facts: impl IntoIterator<Item = &'a SchemaFact>, ) -> Result<Self, Diagnostic>

pub fn dependencies(&self, id: &SchemaFactId) -> Option<&BTreeSet<SchemaFactId>>

Return the direct prerequisites of one fact.

pub fn dependents(&self, id: &SchemaFactId) -> Option<&BTreeSet<SchemaFactId>>

Return the direct dependents of one fact.

pub fn validate_complete(&self) -> Result<(), Diagnostic>
