Struct ErasureCoding

pub struct ErasureCoding {}

Erasure coding abstraction.

Supports creation of parity records and recovery of missing data.

Implementations

impl ErasureCoding

pub fn new() -> Self

Create new erasure coding instance

pub fn extend<'a, SourceIter, ParityIter, SourceBytes, ParityBytes>( &self, source: SourceIter, parity: ParityIter, ) -> Result<(), ErasureCodingError>

where SourceIter: TrustedLen<Item = SourceBytes>, ParityIter: TrustedLen<Item = ParityBytes>, SourceBytes: AsRef<[u8]> + 'a, ParityBytes: AsMut<[u8]> + 'a,

Extend sources using erasure coding

pub fn recover<'a, SourceIter, ParityIter>( &self, source: SourceIter, parity: ParityIter, ) -> Result<(), ErasureCodingError>

where SourceIter: TrustedLen<Item = RecoveryShardState<&'a [u8], &'a mut [u8]>>, ParityIter: TrustedLen<Item = RecoveryShardState<&'a [u8], &'a mut [u8]>>,

Recover missing shards
