Struct LeaseRecord 

pub struct LeaseRecord {
    pub lease_id: u64,
    pub holder: Vec<u8>,
    pub holder_epoch: u64,
    pub ttl_ms: u64,
    pub ts_upper_bound: u64,
    pub expires_at_ms: u64,
    pub superseded: bool,
}

Durable lease state.

lease_id is the acquire-time ts_upper_bound (a committed-high-water value); strict monotonicity of the durable high-water makes it unique across grants, epochs, and failovers.

Fields

lease_id: u64

holder: Vec<u8>

Opaque holder-group key (1..=MAX_LEASE_HOLDER_LEN bytes); compared only for byte equality.

holder_epoch: u64

Supersede ordering within a holder group.

ttl_ms: u64

Acquire-time TTL, re-armed verbatim by every renewal.

ts_upper_bound: u64

Highest physical_ms the holder may stamp. Always a value the durable high-water has reached.

expires_at_ms: u64

Server-clock expiry; the lease stops counting toward the safe frontier at now_ms >= expires_at_ms.

superseded: bool

True once a higher-epoch acquire for the same holder group landed.

Implementations

impl LeaseRecord

pub fn is_expired(&self, now_ms: u64) -> bool

Trait Implementations

impl Clone for LeaseRecord

fn clone(&self) -> LeaseRecord

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeaseRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for LeaseRecord

impl PartialEq for LeaseRecord

fn eq(&self, other: &LeaseRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
