Trait RecordsEncoder 

pub trait RecordsEncoder {
    // Required method
    fn encode_records(
        &mut self,
        sector_id: &SectorId,
        records: &mut [Record],
        abort_early: &AtomicBool,
    ) -> Result<SectorContentsMap>;
}

Records encoder for plotting purposes.

Each record is erasure coded and proofs of space are generated for it. The proofs must be the ones that [TableGenerator::create_proofs()] returns for sector_id.derive_evaluation_seed(piece_offset), because reading and proving create them again the same way. There are exactly [Record::NUM_CHUNKS] of them. The record is then replaced with the chunks at the s-buckets of those proofs, each XORed with the hash of its proof, in s-bucket order. The returned sector contents map has one entry per record with a bit set for each of those s-buckets.

encode_sector() checks the number of entries and the number of bits in each entry, but not which bits are set. Bits that don’t match the proofs result in a sector that can’t be read or proven.

Required Methods

fn encode_records( &mut self, sector_id: &SectorId, records: &mut [Record], abort_early: &AtomicBool, ) -> Result<SectorContentsMap>

Encode provided sector records.

Encoding may stop early once abort_early is set. The returned map is not used in that case.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
