Struct EntryStreamWriter 

pub struct EntryStreamWriter<'b, W: AsyncWrite + Unpin> { /* private fields */ }

An entry writer which supports the streaming of data (ie. the writing of unknown size or data at runtime).

Note

• This writer cannot be manually constructed; instead, use ZipFileWriter::write_entry_stream().
• EntryStreamWriter::close() must be called before a stream writer goes out of scope.
• Utilities for working with AsyncWrite values are provided by AsyncWriteExt.

Implementations

impl<'b, W: AsyncWrite + Unpin> EntryStreamWriter<'b, W>

pub async fn close(self) -> Result<()>

Consumes this entry writer and completes all closing tasks.

This includes:

• Finalising the CRC32 hash value for the written data.
• Calculating the compressed and uncompressed byte sizes.
• Constructing a central directory header.
• Pushing that central directory header to the ZipFileWriter’s store.

Failure to call this function before going out of scope would result in a corrupted ZIP file.

Trait Implementations

impl<'a, W: AsyncWrite + Unpin> AsyncWrite for EntryStreamWriter<'a, W>

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Error>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Error>>

Attempt to close the object.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.
