Function filecoin_proofs_api::update::empty_sector_update_decode_from_range

pub fn empty_sector_update_decode_from_range<R, S, W>(
    registered_proof: RegisteredUpdateProof,
    comm_d: Commitment,
    comm_r: Commitment,
    input_data: R,
    sector_key_data: S,
    output_data: &mut W,

    num_nodes: usize,
) -> Result<()>
where

    W: Write,

Reverses the encoding process for a certain range.

This function is similar to [emptu_sector_update_decode_from], the difference is that it operates directly on the given file descriptions. The current position of the file descriptors is where the decoding starts, i.e. you need to seek to the intended offset before you call this funtion.

Arguments

• registered_proof - Selected sector update proof.
• nodes_count - Total number of nodes within the file.
• comm_d - Data commitment from the updated replica.
• comm_r - Replica commitment of the empty sector.
• input_data - File descriptor to the encoded data.
• sector_key_data - File descriptor to replica of the empty sector.
• output_data - File descriptor where the decoded data is written to.
• nodes_offset - Node offset relative to the beginning of the file.
• num_nodes - Number of nodes to be decoded starting at the current position.
