Struct Reconstructor

Source 
pub struct Reconstructor { /* private fields */ }
Expand description

Reconstructor helps to retrieve blocks from archived pieces.

Implementations§

Source§

impl Reconstructor

Source

pub fn new(erasure_coding: ErasureCoding) -> Self

Create a new instance

Source

pub fn reconstruct_segment( &self, segment_pieces: &[Option<Piece>], ) -> Result<Segment, ReconstructorError>

Given a set of pieces of a segment of the archived history (any half of all pieces are required to be present, the rest will be recovered automatically due to use of erasure coding if needed), reconstructs and returns the segment itself.

Does not modify the internal state of the reconstructor.

Source

pub fn add_segment( &mut self, segment_pieces: &[Option<Piece>], ) -> Result<ReconstructedContents, ReconstructorError>

Given a set of pieces of a segment of the archived history (any half of all pieces are required to be present, the rest will be recovered automatically due to use of erasure coding if needed), reconstructs and returns segment header and a list of encoded blocks with corresponding block numbers.

It is possible to start with any segment, but when next segment is pushed, it needs to follow the previous one or else error will be returned.
