Enum MessageStatus 

pub enum MessageStatus {
    Present {
        position: u64,
        total: u64,
    },
    Truncated {
        dropped: u64,
        oldest_surviving_id: String,
    },
    Unknown,
}

Where one message id turned up, and in what state.

Variants

Present

The id is a line in the record. position is 1-based, oldest first.

Fields

position: u64

total: u64

Truncated

The id is not a line, the header carries a truncation marker, and the id was minted at or before the newest dropped message. A reference an artifact stored is dangling because the record was trimmed — not because the id was never real.

Fields

dropped: u64

oldest_surviving_id: String

Unknown

Anything else: no such id, in a record that has dropped nothing that old.
