Struct Record 

pub struct Record(/* private fields */);

Record contained within a piece.

NOTE: This is a stack-allocated data structure and can cause stack overflow!

Implementations

impl Record

pub const NUM_CHUNKS: usize

Number of chunks within one record.

pub const NUM_S_BUCKETS: usize

Number of s-buckets contained within one sector record.

Essentially we chunk records and erasure code them.

pub const SIZE: usize

Size of a segment record, it is guaranteed to be a multiple of RecordChunk::SIZE

pub fn new_boxed() -> Box<Self>

Create boxed value without hitting stack overflow

pub fn new_zero_vec(length: usize) -> Vec<Self>

Create vector filled with zeroed records without hitting stack overflow

pub fn slice_to_repr(value: &[Self]) -> &[[[u8; 32]; 32768]]

Convenient conversion from slice of record to underlying representation for efficiency purposes.

pub fn slice_from_repr(value: &[[[u8; 32]; 32768]]) -> &[Self]

Convenient conversion from slice of underlying representation to record for efficiency purposes.

pub fn slice_mut_to_repr(value: &mut [Self]) -> &mut [[[u8; 32]; 32768]]

Convenient conversion from mutable slice of record to underlying representation for efficiency purposes.

pub fn slice_mut_from_repr(value: &mut [[[u8; 32]; 32768]]) -> &mut [Self]

Convenient conversion from mutable slice of underlying representation to record for efficiency purposes.

pub fn source_chunks_root(&self) -> RecordChunksRoot

Derive source chunks root on-demand
