Struct SourceLag 

pub struct SourceLag {
    pub bytes: Option<u64>,
    pub events: Option<u64>,
    pub seconds: Option<f64>,
}

Distance from the source’s head, in whichever units the source can measure.

Fields

bytes: Option<u64>

Bytes of unread change log (Postgres WAL, MySQL binlog).

events: Option<u64>

Unread events / messages (Kafka offsets, SQL Server change rows).

seconds: Option<f64>

Age of the oldest unread change, in seconds.

Implementations

impl SourceLag

pub fn bytes(n: u64) -> Self

Lag measured in bytes.

pub fn events(n: u64) -> Self

Lag measured in events.

pub fn seconds(s: f64) -> Self

Lag measured in seconds (negative clock skew clamps to zero).

pub fn is_empty(&self) -> bool

Whether no unit carries a value.

pub fn human(&self) -> String

A compact human rendering: 412 MiB, 1,204 events, 3m 20s, joined.
