Struct iceberg_rust_spec::spec::snapshot::Snapshot

pub struct Snapshot {
    pub snapshot_id: i64,
    pub parent_snapshot_id: Option<i64>,
    pub sequence_number: i64,
    pub timestamp_ms: i64,
    pub manifest_list: String,
    pub summary: Summary,
    pub schema_id: Option<i32>,
}

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.

Fields

snapshot_id: i64

A unique long ID

parent_snapshot_id: Option<i64>

The snapshot ID of the snapshot’s parent. Omitted for any snapshot with no parent

sequence_number: i64

A monotonically increasing long that tracks the order of changes to a table.

timestamp_ms: i64

A timestamp when the snapshot was created, used for garbage collection and table inspection

manifest_list: String

The location of a manifest list for this snapshot that tracks manifest files with additional metadata.

summary: Summary

A string map that summarizes the snapshot changes, including operation.

schema_id: Option<i32>

ID of the table’s current schema when the snapshot was created.

Implementations

impl Snapshot

pub async fn manifests<'metadata>( &self, table_metadata: &'metadata TableMetadata, object_store: Arc<dyn ObjectStore> ) -> Result<impl Iterator<Item = Result<ManifestListEntry, Error>> + 'metadata, Error>

Trait Implementations

impl Clone for Snapshot

fn clone(&self) -> Snapshot

Returns a copy 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 PartialEq for Snapshot

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

This method tests for self and other values to be equal, and is used by ==.

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

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