DecodeSpan decodes the used redundancy level from span keeping the real byte count for the chunk.

EncodeLevel encodes used redundancy level for uploading into span keeping the real byte count for the chunk.

GetReplicaCounts returns back the ascending dispersed replica counts for all redundancy levels.

IsLevelEncoded checks whether the redundancy level is encoded in the span assumes span is LittleEndian.

DefaultLevel is the default redundancy level.

expected 10% chunk retrieval error rate.

expected 1% chunk retrieval error rate.

no redundancy will be added.

expected 50% chunk retrieval error rate.

expected 5% chunk retrieval error rate.

Level is the redundancy level which carries information about how much redundancy should be added to data to remain retrievable with a 1-10^(-6) certainty in different groups of expected chunk retrieval error rates (level values).

ParityChunkCallback is called when a new parity chunk has been created.
