Struct AccessTracker 

pub struct AccessTracker {
    pub access_count: u64,
    pub last_access: u64,
    pub temperature: Temperature,
}

Tracks access patterns for temperature-based tier transitions.

Fields

access_count: u64

Total number of accesses.

last_access: u64

Unix timestamp of the last access (seconds since epoch).

temperature: Temperature

Current temperature tier.

Implementations

impl AccessTracker

pub fn new() -> Self

pub fn recommended_tier(&self) -> Temperature
