Enum ChunkRejection 

pub enum ChunkRejection {
    Invalid,
    MetadataMismatch,
    SenderMismatch,
    TooManyTransfers,
    SenderQuotaExceeded,
    BufferBudgetExhausted,
    PreviouslyFailed,
}

Why FileTransferManager::process_chunk refused a chunk.

Variants

Invalid

Wire fields are malformed or out of bounds: zero or oversized size claims, empty or oversized data, or bytes exceeding the claimed file size.

MetadataMismatch

Chunk metadata does not match the existing assembly for this file id.

SenderMismatch

Chunk sender does not match the sender that started the assembly.

TooManyTransfers

The global concurrent-assembly cap is reached.

SenderQuotaExceeded

The sender’s concurrent-assembly quota is reached.

BufferBudgetExhausted

Accepting the chunk would exceed the global buffered-bytes budget. The affected assembly is dropped along with the chunk: a dropped chunk is never retransmitted, so the transfer could no longer complete and its buffer would only prolong the exhaustion.

PreviouslyFailed

The chunk belongs to a transfer that already failed (resource drop, integrity failure, or stale sweep). Its remaining in-flight chunks are dropped without re-creating assembly state or re-notifying the application — FileReceiveFailed fires at most once per transfer. Retries must use a fresh file_id; the failed id is admitted again only after its tombstone expires (no chunks for the stale timeout).

Implementations

impl ChunkRejection

pub fn is_resource_exhaustion(self) -> bool

true for rejections caused by receiver resource limits rather than malformed input — the cases where a well-formed transfer was lost and the application should be told.

pub fn as_str(self) -> &'static str

Stable machine-readable reason string, carried by the FileReceiveFailed event.
