Struct Writer

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

Writes sparse blocks to a sparse image.

Implementations

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

pub fn new(w: W) -> Result<Self>

Creates a new writer that writes to w.

The created writer skips checksum calculation in favor of speed. To get a writer that does checksum calculation, use Writer::with_crc instead.

pub fn with_crc(w: W) -> Result<Self>

Creates a new writer that writes to w and adds a checksum at the end.

pub fn write_block(&mut self, block: &Block) -> Result<()>

Writes a sparse block to this writer.

The sparse block is converted into the sparse file format and written to this decoder’s destination.

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

Finishes writing the sparse image and flushes any buffered data.

Consumes the reader as using it afterward would be invalid.

Trait Implementations

impl<W: Write + Seek> Drop for Writer<W>

fn drop(&mut self)

Executes the destructor for this type.
