Struct tfrecord::writer::RecordWriterInit

pub struct RecordWriterInit;

The writer initializer.

Implementations

impl RecordWriterInit

pub fn from_writer<T, W>(writer: W) -> Result<RecordWriter<T, W>, Error> where
    T: GenericRecord,
    W: Write, 

Construct a RecordWriter from a type with Write trait.

The constructed RecordWriter enables the blocking send method.

pub fn create<T, P>(path: P) -> Result<RecordWriter<T, BufWriter<File>>, Error> where
    T: GenericRecord,
    P: AsRef<Path>, 

Construct a RecordWriter by creating a file at specified path.

The constructed RecordWriter enables the blocking send method.

pub fn from_async_writer<T, W>(writer: W) -> Result<RecordWriter<T, W>, Error> where
    T: GenericRecord,
    W: AsyncWriteExt, 

Construct a RecordWriter from a type with AsyncWriteExt trait.

The constructed RecordWriter enables the asynchronous send_async method.

pub async fn create_async<T, P>(
    path: P
) -> Result<RecordWriter<T, BufWriter<File>>, Error> where
    T: GenericRecord,
    P: AsRef<Path>, 

Construct a RecordWriter by creating a file at specified path.

The constructed RecordWriter enables the asynchronous send_async method.
