Struct ManifestListWriter

Source 
pub struct ManifestListWriter { /* private fields */ }
Expand description

A manifest list writer.

Implementations§

Source§

impl ManifestListWriter

Source

pub fn next_row_id(&self) -> Option<u64>

Get the next row ID that will be assigned to the next data manifest added.

Source

pub fn v1( output_file: OutputFile, snapshot_id: i64, parent_snapshot_id: Option<i64>, ) -> Self

Construct a v1 ManifestListWriter that writes to a provided OutputFile.

Source

pub fn v2( output_file: OutputFile, snapshot_id: i64, parent_snapshot_id: Option<i64>, sequence_number: i64, ) -> Self

Construct a v2 ManifestListWriter that writes to a provided OutputFile.

Source

pub fn v3( output_file: OutputFile, snapshot_id: i64, parent_snapshot_id: Option<i64>, sequence_number: i64, first_row_id: Option<u64>, ) -> Self

Construct a v3 ManifestListWriter that writes to a provided OutputFile.

Source

pub fn add_manifests( &mut self, manifests: impl Iterator<Item = ManifestFile>, ) -> Result<()>

Append manifests to be written.

If V3 Manifests are added and the first_row_id of any data manifest is unassigned, it will be assigned based on the next_row_id of the writer, and the next_row_id of the writer will be updated accordingly. If first_row_id is already assigned, it will be validated against the next_row_id of the writer.

Source

pub async fn close(self) -> Result<()>

Write the manifest list to the output file.
