Struct AgentEffect 

pub struct AgentEffect {
    pub facts: Vec<Fact>,
    pub proposals: Vec<ProposedFact>,
}

The output of an agent’s execution.

Effects are:

• Immutable once created
• Self-contained
• Merged serially by the engine

Fields

facts: Vec<Fact>

New facts to add to context.

proposals: Vec<ProposedFact>

New proposals to be validated by the engine.

pub fn empty() -> Self

Creates an empty effect (no contributions).

pub fn with_fact(fact: Fact) -> Self

Creates an effect with a single fact.

pub fn with_facts(facts: Vec<Fact>) -> Self

Creates an effect with multiple facts.

pub fn with_proposal(proposal: ProposedFact) -> Self

Creates an effect with a single proposal.

pub fn is_empty(&self) -> bool

Returns true if this effect contributes nothing.

pub fn affected_keys(&self) -> Vec<ContextKey>
