mirai (version 2.2.0)

serial_config: Create Serialization Configuration

Description

Returns a serialization configuration, which may be set to perform custom serialization and unserialization of normally non-exportable reference objects, allowing these to be used seamlessly between different R sessions. This feature utilises the 'refhook' system of R native serialization. Once set, the functions apply to all mirai requests for a specific compute profile.

Usage

serial_config(class, sfunc, ufunc, vec = FALSE)

Value

A list comprising the configuration. This should be passed to the serial argument of daemons().

Arguments

class

character string of the class of object custom serialization functions are applied to, e.g. 'ArrowTabular' or 'torch_tensor'.

sfunc

a function that accepts a reference object inheriting from class (or a list of such objects) and returns a raw vector.

ufunc

a function that accepts a raw vector and returns a reference object (or list of such objects).

vec

[default FALSE] whether or not the serialization functions are vectorized. If FALSE, they should accept and return reference objects individually e.g. arrow::write_to_raw and arrow::read_ipc_stream. If TRUE, they should accept and return a list of reference objects, e.g. torch::torch_serialize and torch::torch_load.

Examples

Run this code
cfg <- serial_config("test_cls", function(x) serialize(x, NULL), unserialize)
