Struct Retention 

pub struct Retention {
    pub max_traces: usize,
    pub retained: usize,
    pub evicted: u64,
    pub oldest_seq: Option<u64>,
    pub truncated: bool,
}

What the ring buffer currently holds, and what it has thrown away.

Fields

max_traces: usize

Configured ceiling (debug.max_traces).

retained: usize

Traces held right now.

evicted: u64

Traces evicted since startup.

oldest_seq: Option<u64>

seq of the oldest trace still held; None when the buffer is empty. Anything older than this is gone.

truncated: bool

Whether anything has been evicted at all. When true, an empty result may mean “rotated out”, not “never happened”.
