    pub current_tier: StorageTier,
    pub access_count: u64,
    pub last_accessed: Instant,

Fields

cid: String

Content identifier string for the block.

current_tier: StorageTier

Current tier assignment.

access_count: u64

Cumulative access count since the record was created.

last_accessed: Instant

Monotonic timestamp of the most-recent access.

Block size in bytes (supplied by the caller on first access).

created_at: Instant

Monotonic timestamp of record creation.

Implementations

impl BlockTierRecord

pub fn access_rate_per_sec(&self, window: Duration) -> f64

Instantaneous access rate over the supplied measurement window.

Returns access_count / window.as_secs_f64(), or 0.0 if the window has zero length (avoids division by zero).
