Properties

availableBytes → int
Free capacity in bytes.
final
diskIndex → int
Zero-based index of this disk in the array.
final
errorLogs → List<String>
Recent error messages collected during I/O operations.
final
hashCode → int
The hash code for this object.
no setteroverride
health → DiskHealth
Current health classification.
final
isFailed → bool
Convenience shorthand — returns true when health is DiskHealth.failed.
no setter
isReadable → bool
Returns true when the disk is either healthy or merely degraded.
no setter
lastChecked → DateTime
Timestamp of last health check.
final
path → String
Filesystem path where this disk's data directory lives.
final
readLatencyMs → double?

final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
totalBytes → int
Total capacity in bytes.
final
usedBytes → int
Bytes actually used on the disk.
no setter
utilizationFraction → double
Fraction of the disk that is in use (0.0 – 1.0).
no setter
utilizationPercentage → double
Utilisation expressed as a percentage (0 – 100).
no setter
writeLatencyMs → double?
Average write latency in milliseconds (null = not measured).

Creates a copy with optional field overrides.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
