Struct HeuristicGate 

pub struct HeuristicGate {
    pub min_output_tokens: u32,
    pub refusal_patterns: Vec<String>,
    pub accept_tool_calls: bool,
    pub escalate_on_max_tokens: bool,
}

Zero-cost heuristic gate (no extra LLM calls).

Fields

min_output_tokens: u32

Minimum output tokens for acceptance (default: 5).

refusal_patterns: Vec<String>

Refusal phrases that trigger escalation.

accept_tool_calls: bool

Accept responses that include tool calls (default: true).

escalate_on_max_tokens: bool

Escalate on MaxTokens stop reason (default: true).

Trait Implementations

impl ConfidenceGate for HeuristicGate

fn accept( &self, _request: &CompletionRequest, response: &CompletionResponse, ) -> bool

Return true if the response is good enough to accept without escalating to a higher tier.

impl Default for HeuristicGate

fn default() -> Self

Returns the “default value” for a type.
