RaidConfig class

Immutable configuration object passed to FilesystemRaid.

Example:

const config = RaidConfig(
  type: RaidType.raid5,
  diskCount: 3,
  enableCompression: true,
);

RaidConfig({required RaidType type, required int diskCount, bool enableCompression = false, bool enableEncryption = false, List<int>? encryptionKey, int chunkSize = _defaultChunkSize, Duration healthCheckInterval = const Duration(hours: 24), ParityAlgorithm parityAlgorithm = ParityAlgorithm.xor, int maxRetries = 3, bool writeVerification = true, RaidLogLevel logLevel = RaidLogLevel.info}): Creates a RaidConfig.
const

chunkSize → int: Size in bytes of each stripe chunk (default 4 MiB).
final
diskCount → int: Number of physical disks (must match the diskPaths list length).
final
enableCompression → bool: Compress chunk data before writing (DEFLATE).
final
enableEncryption → bool: Encrypt chunk data with AES-256-CBC before writing.
final
encryptionKey → List<int>?: 32-byte AES key. Required when enableEncryption is true.
final
faultTolerance → int: Number of tolerated disk failures before data loss.
no setter
hashCode → int: The hash code for this object.
no setterinherited
healthCheckInterval → Duration: How often the background health checker inspects disk status.
final
logLevel → RaidLogLevel: Verbosity of the internal logger.
final
maxRetries → int: Number of I/O retry attempts on transient errors.
final
parityAlgorithm → ParityAlgorithm: Parity algorithm used when type is RaidType.raid5.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
storageEfficiency → double: Storage efficiency (usable / total capacity).
no setter
type → RaidType: RAID level.
final
writeVerification → bool: Re-read every chunk after write to verify data integrity.
final

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.
