Struct StreamingZipWriter 

pub struct StreamingZipWriter<W: Write + Seek> { /* private fields */ }

Streaming ZIP writer that compresses data on-the-fly

Implementations

impl StreamingZipWriter<File>

pub fn new<P: AsRef<Path>>(path: P) -> Result<Self>

Create a new ZIP writer with default compression level (6) using DEFLATE

pub fn with_compression<P: AsRef<Path>>( path: P, compression_level: u32, ) -> Result<Self>

Create a new ZIP writer with custom compression level (0-9) using DEFLATE

pub fn with_method<P: AsRef<Path>>( path: P, method: CompressionMethod, compression_level: u32, ) -> Result<Self>

Create a new ZIP writer with specified compression method and level

Arguments

• path - Path to the output ZIP file
• method - Compression method to use (Deflate, Zstd, or Stored)
• compression_level - Compression level (0-9 for DEFLATE, 1-21 for Zstd)

impl<W: Write + Seek> StreamingZipWriter<W>

pub fn from_writer(writer: W) -> Result<Self>

Create a new ZIP writer from an arbitrary writer with default compression level (6) using DEFLATE

pub fn from_writer_with_compression( writer: W, compression_level: u32, ) -> Result<Self>

Create a new ZIP writer from an arbitrary writer with custom compression level

pub fn from_writer_with_method( writer: W, method: CompressionMethod, compression_level: u32, ) -> Result<Self>

Create a new ZIP writer from an arbitrary writer with specified compression method and level

Arguments

• writer - Any writer implementing Write + Seek
• method - Compression method to use (Deflate, Zstd, or Stored)
• compression_level - Compression level (0-9 for DEFLATE, 1-21 for Zstd)

pub fn start_entry(&mut self, name: &str) -> Result<()>

Start a new entry (file) in the ZIP

pub fn write_data(&mut self, data: &[u8]) -> Result<()>

Write uncompressed data to current entry (will be compressed on-the-fly)

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

Finish ZIP file (write central directory and return the writer)
