Struct FastqWriter 

pub struct FastqWriter { /* private fields */ }

A FASTQ writer that writes bgzf-compressed output.

The inner writer handles BGZF block framing and compression. Use new for single-threaded compression or from_writer to supply a pre-configured writer (e.g. a pooled_writer::PooledWriter for multi-threaded compression).

Implementations

impl FastqWriter

pub fn new(path: &Path, compression: u8) -> Result<Self>

Create a new single-threaded FASTQ writer at the given path.

Uses noodles-bgzf with the specified compression level (0-12).

Errors

Returns an error if the file cannot be created or the compression level is invalid.

pub fn from_writer(writer: impl Write + 'static) -> Self

Create a FASTQ writer from an existing writer that handles BGZF compression (e.g. a pooled_writer::PooledWriter).

pub fn write_read(&mut self, read: &SimulatedRead) -> Result<()>

Write a single read as a FASTQ record.

Writes the four-line FASTQ format:

@read_name
BASES
+
QUALITIES

Errors

Returns an error if writing fails.

pub fn close(self)

Finalize the FASTQ file.

Drops the underlying writer, which flushes any buffered data and (for BGZF writers) writes the EOF marker. For pooled writers, this sends remaining data to the compression pool.
