Struct icu_provider_blob::export::BlobExporter

pub struct BlobExporter<'w> { /* private fields */ }

A data exporter that writes data to a single-file blob. See the module-level docs for an example.

Implementations

impl<'w> BlobExporter<'w>

pub fn new_with_sink(sink: Box<dyn Write + Sync + 'w>) -> Self

Creates a version 1 BlobExporter that writes to the given I/O stream.

Version 1 is needed if the blob may be consumed by ICU4X versions 1.0 through 1.3. If targeting only ICU4X 1.4 and above, see BlobExporter::new_with_sink().

Trait Implementations

impl DataExporter for BlobExporter<'_>

fn put_payload( &self, marker: DataMarkerInfo, id: DataIdentifierBorrowed<'_>, payload: &DataPayload<ExportMarker>, ) -> Result<(), DataError>

Save a payload corresponding to the given marker and locale.

fn flush( &self, marker: DataMarkerInfo, _metadata: FlushMetadata, ) -> Result<(), DataError>

Function called after a non-singleton marker has been fully enumerated.

fn close(&mut self) -> Result<ExporterCloseMetadata, DataError>

This function has to be called before the object is dropped (after all markers have been fully dumped). This conceptually takes ownership, so clients may not interact with this object after close has been called.

fn flush_singleton( &self, marker: DataMarkerInfo, payload: &DataPayload<ExportMarker>, metadata: FlushMetadata, ) -> Result<(), DataError>

Function called for singleton markers.

impl Debug for BlobExporter<'_>

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

Formats the value using the given formatter.
