Struct FiveHourBlock 

pub struct FiveHourBlock {
    pub start: Timestamp,
    pub actual_last_activity: Timestamp,
    pub token_counts: TokenCounts,
    pub models: Vec<String>,
    pub usage_limit_reset: Option<Timestamp>,
}

Active 5-hour billing block. start is the UTC-floor-to-hour of the block’s first entry; actual_last_activity lets the caller distinguish a block where the user stopped typing 10 seconds ago from one where they stopped 4 hours ago. The block’s end time is a derivation from start — see Self::end.

Fields

start: Timestamp

actual_last_activity: Timestamp

token_counts: TokenCounts

models: Vec<String>

usage_limit_reset: Option<Timestamp>

usageLimitResetTime from the most recent entry that carried one. Verified absent across the surveyed Claude Code corpus (lsm-ghpj, 2026-05-16); the field is deserialized defensively but segments do not consume it — rate_limit_5h_reset uses block.end() per ADR-0013.

Implementations

impl FiveHourBlock

pub fn end(&self) -> Timestamp

Nominal close of the block: start + BLOCK_DURATION_HOURS. Derived rather than stored so the invariant can’t drift from start after construction.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
