Struct npyz::npz::NpzWriter

pub struct NpzWriter<W: Write + Seek> { /* fields omitted */ }

Interface for writing an NPZ file.

This is only available with the "npz" feature.

Implementations

impl NpzWriter<BufWriter<File>>

pub fn create(path: impl AsRef<Path>) -> Result<Self>

Create a new, empty npz archive on the filesystem. (will clobber an existing file)

impl<W: Write + Seek> NpzWriter<W>

pub fn new(writer: W) -> Self

Begin writing an NPZ file to an arbitrary writer.

pub fn array<T: Serialize + ?Sized>(
    &mut self,
    name: &str,
    options: FileOptions
) -> Result<NpzWriterBuilder<'_, T, W>>

Begin an entry in the NPZ for the corresponding array.

The returned object implements the WriterBuilder trait. You must import this trait and use its methods to continue configuring the object and begin writing.

pub fn zip_writer(&mut self) -> &mut ZipWriter<W>

Exposes the underlying zip::ZipWriter.
