Runic.Workflow.Facts (Runic v0.1.0-alpha.7)

Unified accessors for Fact and FactRef structs.

Avoids pattern-matching on struct types throughout the codebase when only the hash, ancestry, or "has a value?" predicate is needed.

Summary

ancestry(arg1)

Returns the ancestry of a Fact or FactRef.

hash(arg1)

Returns the hash of a Fact or FactRef.

to_ref(fact)

Converts a Fact to a FactRef, discarding the value.

value?(arg1)

Returns true if the struct carries a concrete value (only true for Facts with non-nil values).

@spec ancestry(Runic.Workflow.Fact.t() | Runic.Workflow.FactRef.t()) ::
  {Runic.Workflow.Fact.hash(), Runic.Workflow.Fact.hash()} | nil

Returns the ancestry of a Fact or FactRef.

@spec hash(Runic.Workflow.Fact.t() | Runic.Workflow.FactRef.t()) ::
  Runic.Workflow.Fact.hash()

Returns the hash of a Fact or FactRef.

@spec to_ref(Runic.Workflow.Fact.t()) :: Runic.Workflow.FactRef.t()

Converts a Fact to a FactRef, discarding the value.

@spec value?(Runic.Workflow.Fact.t() | Runic.Workflow.FactRef.t()) :: boolean()

Returns true if the struct carries a concrete value (only true for Facts with non-nil values).
