Struct GenericKeyedChunkWriter

Source

pub struct GenericKeyedChunkWriter<K: RawSortKey> { /* private fields */ }

Expand description

Generic writer for keyed temp chunks with pre-computed sort keys.

Works with any type implementing RawSortKey. Supports optional BGZF compression for reduced disk usage.

Implementations§

Source §

impl<K: RawSortKey> GenericKeyedChunkWriter<K>

Source

pub fn create( path: &Path, compression_level: u32, threads: usize, ) -> Result<Self>

Create a new keyed chunk writer with optional compression.

compression_level 0 = uncompressed (fastest, uses most disk).
compression_level > 0 = BGZF compression at specified level.
threads > 1 enables multi-threaded compression.

§Errors

Returns an error if the output file cannot be created.

§Panics

Panics if threads is greater than 1 but NonZero::new receives zero.

Source

pub fn write_record(&mut self, key: &K, record: &[u8]) -> Result<()>

Write a keyed record.

§Errors

Returns an error if writing to the underlying writer fails.

Source

pub fn finish(self) -> Result<()>

Finish writing and flush.

§Errors

Returns an error if flushing the writer fails.
