Expand description
IPC write options used to control the behaviour of the IpcDataGenerator
Fields§
§alignment: u8
Write padding after memory buffers to this multiple of bytes. Must be 8, 16, 32, or 64 - defaults to 64.
write_legacy_ipc_format: bool
The legacy format is for releases before 0.15.0, and uses metadata V4
metadata_version: MetadataVersion
The metadata version to write. The Rust IPC writer supports V4+
Default versions per crate
When creating the default IpcWriteOptions, the following metadata versions are used:
version 2.0.0: V4, with legacy format enabled version 4.0.0: V5
batch_compression_type: Option<CompressionType>
Compression, if desired. Will result in a runtime error if the corresponding feature is not enabled
Implementations§

pub fn try_with_compression( self, batch_compression_type: Option<CompressionType>, ) -> Result<Self, ArrowError>
Configures compression when writing IPC files.
Will result in a runtime error if the corresponding feature is not enabled
