Struct RejectCounts 

pub struct RejectCounts {
    pub malformed: u64,
    pub epoch: u64,
    pub shape: u64,
    pub delivered: u64,
    pub window: u64,
    pub block_shape: u64,
    pub delivered_lo: Option<u32>,
    pub delivered_hi: Option<u32>,
    pub seen_lo: Option<u32>,
    pub seen_hi: Option<u32>,
}

Datagrams a Decoder refused at ingest, one counter per reason.

A shard that reaches the process and is then dropped leaves no other trace: the window simply does not advance. These counters are that trace. A stalled window whose epoch count is climbing is being fed by a peer whose session stamp disagrees with the one adopted; one whose delivered count is climbing is being fed blocks it has already emitted.

Fields

malformed: u64

Not a DATA datagram, or shorter than the fixed header.

epoch: u64

Carries a session epoch other than the one this decoder holds.

shape: u64

Header shard geometry is unusable: no data shards, more shards than the codeword allows, or an index outside the codeword.

delivered: u64

Names a block already delivered to the caller.

window: u64

Names a block beyond the reassembly window’s ceiling.

block_shape: u64

Shard length or codeword shape disagrees with the block it would join, which symbol-wise FEC cannot mix.

delivered_lo: Option<u32>

Lowest and highest block id refused as already delivered. A stalled window names which blocks are being re-offered, which separates surplus parity on the block just completed from a peer replaying a range the window passed long ago.

delivered_hi: Option<u32>

seen_lo: Option<u32>

Lowest and highest block id SEEN at ingest, recorded before any gate runs. A block the encoder says it sent that never appears here was lost below the decoder; one that appears without advancing the window was taken by a path that neither delivers nor refuses.

seen_hi: Option<u32>
