Implementations

impl BackendSelector

pub fn new() -> Self

Create a new backend selector with default settings

pub fn with_privacy(self, tier: PrivacyTier) -> Self

Set privacy tier

pub fn with_latency(self, tier: LatencyTier) -> Self

Set latency tier

pub fn with_throughput(self, tier: ThroughputTier) -> Self

Set throughput tier

pub fn with_cost(self, tier: CostTier) -> Self

Set cost tier

pub fn disable(self, backend: ServingBackend) -> Self

Disable a specific backend

pub fn prefer(self, backend: ServingBackend) -> Self

Add a preferred backend

pub fn recommend(&self) -> Vec<ServingBackend>

Recommend backends based on requirements

pub fn is_valid(&self, backend: ServingBackend) -> bool

Check if a backend is valid for current configuration

pub fn validate(&self, backend: ServingBackend) -> Result<(), PrivacyViolation>

Validate a request against privacy tier (Poka-Yoke gate)

Returns Err if the backend would violate privacy constraints.
