Type Interfaces#

Here are the basic types for events, html and three.js elements, and others.

class zaku.interfaces.BytesIO#

Bases: _BufferedIOBase

Buffered I/O implementation using an in-memory bytes buffer.

__init__(*args, **kwargs)#
__new__(**kwargs)#
close()#

Disable all I/O operations.

closed#

True if the file is closed.

flush()#

Does nothing.

getbuffer()#

Get a read-write view over the contents of the BytesIO object.

getvalue()#

Retrieve the entire contents of the BytesIO object.

isatty()#

Always returns False.

BytesIO objects are not connected to a TTY-like device.

read(size=-1, /)#

Read at most size bytes, returned as a bytes object.

If the size argument is negative, read until EOF is reached. Return an empty bytes object at EOF.

read1(size=-1, /)#

Read at most size bytes, returned as a bytes object.

If the size argument is negative or omitted, read until EOF is reached. Return an empty bytes object at EOF.

readable()#

Returns True if the IO object can be read.

readinto(buffer, /)#

Read bytes into buffer.

Returns number of bytes read (0 for EOF), or None if the object is set not to block and has no data to read.

readline(size=-1, /)#

Next line from the file, as a bytes object.

Retain newline. A non-negative size argument limits the maximum number of bytes to return (an incomplete line may be returned then). Return an empty bytes object at EOF.

readlines(size=None, /)#

List of bytes objects, each a line from the file.

Call readline() repeatedly and return a list of the lines so read. The optional size argument, if given, is an approximate bound on the total number of bytes in the lines returned.

seek(pos, whence=0, /)#

Change stream position.

Seek to byte offset pos relative to position indicated by whence:

0 Start of stream (the default). pos should be >= 0; 1 Current position - pos may be negative; 2 End of stream - pos usually negative.

Returns the new absolute position.

seekable()#

Returns True if the IO object can be seeked.

tell()#

Current file position, an integer.

truncate(size=None, /)#

Truncate the file to at most size bytes.

Size defaults to the current file position, as returned by tell(). The current file position is unchanged. Returns the new size.

writable()#

Returns True if the IO object can be written.

write(b, /)#

Write bytes to file.

Return the number of bytes written.

writelines(lines, /)#

Write lines to the file.

Note that newlines are not added. lines can be any iterable object producing bytes-like objects. This is equivalent to calling write() for each element.

class zaku.interfaces.ZData[source]#

Bases: object

This converts arrays and tensors to z-format.

Parameters:

data (torch.Tensor | ndarray) –

static decode(zdata)[source]#
class zaku.interfaces.Payload[source]#

Bases: SimpleNamespace

__init__(_greedy=None, **payload)[source]#

Return type:

Dict
