[][src]Module solana_ledger::shred

The shred module defines data structures and methods to pull MTU sized data frames from the network.

Structs

CodingShredHeader

The coding shred header has FEC information

DataShredHeader

The data shred header has parent offset and flags

Shred
ShredCommonHeader

A common header that is present in data and code shred headers

Enums

ShredError

Constants

CODING_SHRED
DATA_COMPLETE_SHRED
DATA_SHRED

The constants that define if a shred is data or coding

MAX_DATA_SHREDS_PER_FEC_BLOCK
OFFSET_OF_SHRED_INDEX
OFFSET_OF_SHRED_SLOT
OFFSET_OF_SHRED_TYPE
RECOMMENDED_FEC_RATE
SHRED_PAYLOAD_SIZE
SHRED_TICK_REFERENCE_MASK
SIZE_OF_CODING_SHRED_HEADER
SIZE_OF_COMMON_SHRED_HEADER

The following constants are computed by hand, and hardcoded. test_shred_constants ensures that the values are correct. Constants are used over lazy_static for performance reasons.

SIZE_OF_DATA_SHRED_HEADER
SIZE_OF_DATA_SHRED_IGNORED_TAIL
SIZE_OF_DATA_SHRED_PAYLOAD
SIZE_OF_NONCE
SIZE_OF_SHRED_INDEX
SIZE_OF_SHRED_SLOT
SIZE_OF_SHRED_TYPE
SIZE_OF_SIGNATURE
