Struct TruncationMarker 

pub struct TruncationMarker {
    pub dropped: u64,
    pub oldest_surviving_id: String,
    pub last_dropped_id: String,
    pub at_ms: u64,
}

What one record has already dropped from its front.

Cumulative over the record’s life: dropped is every message truncation has ever taken from this record, not what the last one took.

Fields

dropped: u64

oldest_surviving_id: String

The msg_ id of the oldest message still in the file.

last_dropped_id: String

The msg_ id of the newest message that went. A reference to any message minted at or before this one reads as truncated rather than as unknown — see crate::retention::locate_message.

at_ms: u64

When the most recent truncation ran, in milliseconds since the epoch.
