serial_config: Create Serialization Configuration

In nanonext: NNG (Nanomsg Next Gen) Lightweight Messaging Library

Create Serialization Configuration

Description

Returns a serialization configuration, which may be set on a Socket for custom serialization and unserialization of non-system reference objects, allowing these to be sent and received between different R sessions. This utilises the 'refhook' system of R native serialization. Once set, the functions apply to all send and receive operations performed in mode "serial" over the Socket or Context created from the Socket.

Usage

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

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.

Value

A list comprising the configuration. This should be set on a Socket using opt<-() with option name "serial".

Examples

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

s <- socket()
opt(s, "serial") <- cfg

# provide an empty list to remove registered functions
opt(s, "serial") <- list()
