Struct QualityConfig 

pub struct QualityConfig {
    pub self_check: bool,
    pub proposer_provider: ProviderName,
    pub checker_provider: ProviderName,
    pub trigger: TriggerPolicy,
    pub min_evidence: f32,

}

Configuration for the MARCH self-check quality pipeline.

Add a [quality] section to your config.toml to enable:

[quality]
self_check = true
trigger = "has_retrieval"
async_run = false

Fields

self_check: bool

Enable post-response self-check pipeline.

proposer_provider: ProviderName

Advisory: preferred provider for the Proposer role.

In MVP this field is parsed but not acted upon — the main provider is used. Tracked as a follow-up issue.

checker_provider: ProviderName

Advisory: preferred provider for the Checker role.

In MVP this field is parsed but not acted upon — the main provider is used. Tracked as a follow-up issue.

trigger: TriggerPolicy

When to trigger the self-check pipeline.

min_evidence: f32

Minimum evidence strength to consider an assertion supported (0.0–1.0).

Assertions where status != Irrelevant && evidence < min_evidence are flagged.

async_run: bool

If false (default), self-check blocks the response until complete. If true, it runs in the background and emits a visible closing marker.

latency_budget_ms: u64

Hard ceiling on total pipeline latency in milliseconds (sync mode).

per_call_timeout_ms: u64

Per-LLM-call timeout in milliseconds. Must be ≤ latency_budget_ms / 2.

max_assertions: usize

Maximum number of assertions to extract from one response.

max_response_chars: usize

Skip pipeline when assistant response exceeds this many characters.

cache_disabled_for_checker: bool

If true, Checker provider clones without prompt-cache emission (recommended).

flag_marker: String

String appended to the assistant response when the pipeline flags issues.

Implementations

impl QualityConfig

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

Validate consistency constraints.

Errors

Returns an error if 2 * per_call_timeout_ms > latency_budget_ms or min_evidence is outside [0.0, 1.0].

Trait Implementations

impl Clone for QualityConfig

fn clone(&self) -> QualityConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for QualityConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for QualityConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for QualityConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&QualityConfig> for QualityConfig

fn from(c: &QualityConfig) -> Self

Converts to this type from the input type.

impl Serialize for QualityConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
