Struct Snapshot

pub struct Snapshot { /* private fields */ }

A snapshot represents the state of a table at some time and is used to access the complete set of data files in the table.

Implementations

impl Snapshot

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

Create a builder for building Snapshot. On the builder, call .snapshot_id(...), .parent_snapshot_id(...)(optional), .sequence_number(...), .timestamp_ms(...), .manifest_list(...), .summary(...), .schema_id(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of Snapshot.

impl Snapshot

pub fn snapshot_id(&self) -> i64

Get the id of the snapshot

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

Get parent snapshot id.

pub fn sequence_number(&self) -> i64

Get sequence_number of the snapshot. Is 0 for Iceberg V1 tables.

pub fn manifest_list(&self) -> &str

Get location of manifest_list file

pub fn summary(&self) -> &Summary

Get summary of the snapshot

pub fn timestamp(&self) -> Result<DateTime<Utc>>

Get the timestamp of when the snapshot was created

pub fn timestamp_ms(&self) -> i64

Get the timestamp of when the snapshot was created in milliseconds

pub fn schema_id(&self) -> Option<SchemaId>

Get the schema id of this snapshot.

pub fn schema(&self, table_metadata: &TableMetadata) -> Result<SchemaRef>

Get the schema of this snapshot.

pub async fn load_manifest_list( &self, file_io: &FileIO, table_metadata: &TableMetadata, ) -> Result<ManifestList>

Load manifest list.

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Snapshot

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Snapshot

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Snapshot

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

impl Serialize for Snapshot

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Snapshot
