Struct InnerPiece 

#[repr(C)]
pub struct InnerPiece {
    pub header: PieceHeader,
    pub record: Record,
}

A piece of archival history.

This version is allocated on the stack, for a heap-allocated piece that can be moved around efficiently, see Piece.

Internally, a piece contains a record, supplementary record chunk root, and a proof proving this piece belongs to can be used to verify that a piece belongs to the actual archival history of the blockchain.

Fields

header: PieceHeader

Piece header

record: Record

Record contained within a piece

Implementations

impl InnerPiece

pub const SIZE: usize

Size of a piece (in bytes)

pub fn new_boxed() -> Box<Self>

Create boxed value without hitting stack overflow

pub fn is_valid( &self, super_segment_root: &SuperSegmentRoot, num_segments: u32, position: PiecePosition, ) -> bool

Check whether the piece is valid against the matching super segment root

pub fn record_root(&self) -> RecordRoot

Root of the record contained within a piece.

It is re-derived on every call of this function.

pub fn slice_to_repr(value: &[Self]) -> &[[u8; 1049560]]

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

pub fn slice_from_repr(value: &[[u8; 1049560]]) -> &[Self]

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

pub fn slice_mut_to_repr(value: &mut [Self]) -> &mut [[u8; 1049560]]

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

pub fn slice_mut_from_repr(value: &mut [[u8; 1049560]]) -> &mut [Self]

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