Struct RecordedHistorySegment

Source 
pub struct RecordedHistorySegment(/* private fields */);
Expand description

Recorded history segment before archiving is applied.

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

Implementations§

Source§

impl RecordedHistorySegment

Source

pub const NUM_RAW_RECORDS: usize = 128usize

Number of raw records in one segment of recorded history.

Source

pub const ERASURE_CODING_RATE: (usize, usize)

Erasure coding rate for records during archiving process.

Source

pub const SIZE: usize = 130_023_424usize

Size of recorded history segment in bytes.

It includes half of the records (just source records) that will later be erasure coded and together with corresponding commitments and witnesses will result in ArchivedHistorySegment::NUM_PIECES Pieces of archival history.

Source

pub fn new_boxed() -> Box<Self>

Create boxed value without hitting stack overflow
