Struct CacheUse 

pub struct CacheUse { /* private fields */ }

One prefix’s cache as last seen: when a real request carried it, in milliseconds, and whether that use still owes its one renewal.

The renewal is recorded rather than inferred from the times, so the bound of one renewal per real use holds whatever lead a caller passes (kernel D62).

Implementations

impl CacheUse

pub fn sent(at_ms: u64) -> CacheUse

A real request carrying the prefix was sent at at_ms; the use owes one renewal.

pub fn renewed(self) -> CacheUse

The renewal this use owed has been sent; the use owes none until the next real request.
