Struct ManifestEntry

pub struct ManifestEntry {
    pub status: ManifestStatus,
    pub snapshot_id: Option<i64>,
    pub sequence_number: Option<i64>,
    pub file_sequence_number: Option<i64>,
    pub data_file: DataFile,
}

A manifest is an immutable Avro file that lists data files or delete files, along with each file’s partition data tuple, metrics, and tracking information.

Fields

status: ManifestStatus

field: 0

Used to track additions and deletions.

snapshot_id: Option<i64>

field id: 1

Snapshot id where the file was added, or deleted if status is 2. Inherited when null.

sequence_number: Option<i64>

field id: 3

Data sequence number of the file. Inherited when null and status is 1 (added).

file_sequence_number: Option<i64>

field id: 4

File sequence number indicating when the file was added. Inherited when null and status is 1 (added).

data_file: DataFile

field id: 2

File path, partition tuple, metrics, …

Implementations

impl ManifestEntry

pub fn builder() -> ManifestEntryBuilder<((), (), (), (), ())>

Create a builder for building ManifestEntry. On the builder, call .status(...), .snapshot_id(...)(optional), .sequence_number(...)(optional), .file_sequence_number(...)(optional), .data_file(...) to set the values of the fields. Finally, call .build() to create the instance of ManifestEntry.

impl ManifestEntry

pub fn is_alive(&self) -> bool

Check if this manifest entry is deleted.

pub fn status(&self) -> ManifestStatus

Status of this manifest entry

pub fn content_type(&self) -> DataContentType

Content type of this manifest entry.

pub fn file_format(&self) -> DataFileFormat

File format of this manifest entry.

pub fn file_path(&self) -> &str

Data file path of this manifest entry.

pub fn record_count(&self) -> u64

Data file record count of the manifest entry.

pub fn snapshot_id(&self) -> Option<i64>

Snapshot id

pub fn sequence_number(&self) -> Option<i64>

Data sequence number.

pub fn file_size_in_bytes(&self) -> u64

File size in bytes.

pub fn data_file(&self) -> &DataFile

get a reference to the actual data file

Trait Implementations

impl Clone for ManifestEntry

fn clone(&self) -> ManifestEntry

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ManifestEntry

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

Formats the value using the given formatter.

impl PartialEq for ManifestEntry

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