Enum Tier 

pub enum Tier {
    Core,
    Curated,
    BestEffort,
}

Accuracy-evidence tier for a supported bankswitch scheme.

The tier is an honesty marker, not a behavioural one: runtime behaviour is identical regardless of tier — it records only how much external evidence backs the board’s correctness, so accuracy claims stay precise as the long-tail scheme set grows. The honesty gate (tests/mapper_tier_honesty.rs) forbids a BestEffort board ever backing the accuracy oracle.

Variants

Core

Spec-implemented + oracle-gated (AccuracyCoin-equivalent / commercial ROM byte-identity). The bedrock schemes.

Curated

Long-tail board added with concrete game demand plus a redistributable fixture or spec; register-decode unit-tested and boot-smoked.

BestEffort

Reference-ported long-tail with no redistributable fixture; register-decode tested only, and structurally never accuracy-gated.

Implementations

impl Tier

pub const fn name(self) -> &'static str

Human-readable tier name (docs generation, UI badges, logs).

pub const fn is_accuracy_gated(self) -> bool

Whether this tier is covered by the accuracy oracle gate. Core and Curated are; BestEffort is not. This is the load-bearing predicate the honesty gate asserts.

Trait Implementations

impl Clone for Tier

fn clone(&self) -> Tier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Tier

fn deserialize<__D>( __deserializer: __D, ) -> Result<Tier, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Tier

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Tier

fn eq(&self, other: &Tier) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Tier

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Tier
