Struct Q42VolumeManifest 

pub struct Q42VolumeManifest {
    pub generation: u64,
    pub segments: Vec<Q42VolumeSegment>,
    pub lexicon_segments: Vec<Q42LexiconSegment>,
}

Front-embedded catalog which makes immutable Q42 segments one snapshot.

Fields

generation: u64

segments: Vec<Q42VolumeSegment>

lexicon_segments: Vec<Q42LexiconSegment>

Implementations

impl Q42VolumeManifest

pub fn encode(&self) -> Result<Vec<u8>>

pub fn decode(bytes: &[u8]) -> Result<Self>

pub fn validate(&self) -> Result<()>

pub fn segment_range_for_object( &self, object_hash: u64, ) -> Option<Q42SegmentMatchRange>

Return every segment whose committed object interval can contain the given value. Equal boundaries remain complete across adjacent volumes.

pub fn segment_indices_for_object_into( &self, object_hash: u64, cursor: usize, out: &mut [usize], ) -> Result<Option<Q42SegmentMatchPage>>

Fill a bounded page of matching segment indices. This caps caller work even when a high-frequency object falls on many volume boundaries.

pub fn segment_from_file( path: &Path, locator: String, ) -> Result<Q42VolumeSegment>

pub fn lexicon_segment_from_file( path: &Path, locator: String, ) -> Result<Q42LexiconSegment>

Trait Implementations

impl Clone for Q42VolumeManifest

fn clone(&self) -> Q42VolumeManifest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Q42VolumeManifest

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

Formats the value using the given formatter.

impl PartialEq for Q42VolumeManifest

fn eq(&self, other: &Q42VolumeManifest) -> 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.
