Function read_sector_record_chunks 

Source 
pub async fn read_sector_record_chunks<S, A>(
    piece_offset: PieceOffset,
    pieces_in_sector: u16,
    s_bucket_offsets: &[u32; 65536],
    sector_contents_map: &SectorContentsMap,
    pos_proofs: &PosProofs,
    sector: &ReadAt<S, A>,
) -> Result<SectorRecordChunks, ReadingError>

    A: ReadAtAsync,
Expand description

Read sector record chunks, only plotted s-buckets are marked as present (in decoded form).

Returns ReadingError::PosProofsMismatch if the sector contents map has no entry for piece_offset, or if the record’s chunks in it are not at exactly the s-buckets of pos_proofs. Each chunk was encoded with the proof for its s-bucket, so chunks can’t be decoded correctly otherwise.

NOTE: This is an async function, but it also does CPU-intensive operation internally, while it is not very long, make sure it is okay to do so in your context.
