Parsed nsfdb_database_information2_t.

Fields

last_fixup_time: Timedate

Most recent fix-up (compact/recovery) timestamp.

database_quota_limit: u32

Per-database quota limit. Operator-defined; zero means unlimited.

database_quota_warn_threshold: u32

Per-database quota warn threshold.

unknown_time1: Timedate

First of two undocumented TIMEDATEs in this block.

unknown_time2: Timedate

Second of two undocumented TIMEDATEs in this block.

object_store_replica_identifier: Timedate

Object store replica identifier (TIMEDATE-shaped opaque).

superblocks: [SuperblockSlot; 4]

Four superblock copies. Pick the freshest via the crate::superblock helpers.

maximum_extension_granularity: u32

Maximum allowed extension granularity for file growth.

summary_bucket_granularity: u16

Allocation granularity for summary buckets.

non_summary_bucket_granularity: u16

Allocation granularity for non-summary buckets.

minimum_summary_bucket_size: u32

Lower bound on summary-bucket size.

minimum_non_summary_bucket_size: u32

Lower bound on non-summary-bucket size.

maximum_summary_bucket_size: u32

Upper bound on summary-bucket size.

maximum_non_summary_bucket_size: u32

Upper bound on non-summary-bucket size.

non_summary_append_size: u16

Size in bytes that non-summary appends grow by.

non_summary_append_factor: u16

Append factor (growth multiplier for non-summary regions).

summary_bucket_fill_factor: u16

Fill factor target for summary buckets.

non_summary_bucket_fill_factor: u16

Fill factor target for non-summary buckets.

bdbs: [BdbSlot; 2]

Two BDB copies (primary + write-ahead redundancy).

Implementations

impl Information2

pub fn parse(bytes: &[u8]) -> Result<Self, NsfError>

Parse Information2 from the 124 bytes starting at INFO2_FILE_OFFSET within a full-file buffer. The caller is responsible for slicing the right window; this method only checks the slice length.

pub fn populated_superblock_indices(&self) -> Vec<usize>

Slot indices 0..=3 of populated superblocks (any with non-zero position or size).

pub fn populated_bdb_indices(&self) -> Vec<usize>

Slot indices 0..=1 of populated BDBs.

Trait Implementations

impl Clone for Information2

fn clone(&self) -> Information2

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Information2

impl Debug for Information2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Information2

impl PartialEq for Information2

fn eq(&self, other: &Information2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
