Struct HostPreferences 

pub struct HostPreferences { /* private fields */ }

Per-host renderer preference cache. Cheap to clone (Arc inside).

Implementations

impl HostPreferences

pub fn new(capacity: u64, ttl: Duration) -> Self

pub fn with_defaults() -> Self

pub async fn record_failure( &self, host: &str, kind: &FailoverErrorKind, ) -> Option<RendererKind>

Record a failure for host (will be normalized). Returns the promotion target if this call promoted the host, else None.

pub async fn record_success(&self, host: &str)

Record a successful render for host (will be normalized).

pub async fn preferred(&self, host: &str) -> Option<RendererKind>

Returns the preferred renderer for host if a promotion is in effect, else None (caller falls back to default chain).

pub async fn reset_all(&self)

Clear all preference state.

pub async fn reset_host(&self, host: &str)

Clear preference state for a specific host (will be normalized).

pub fn size(&self) -> u64

Current cache size (approximate).
