rds_to_qs: RDS to qs2 format

In qs2: Efficient Serialization of R Objects

RDS to qs2 format

Description

Converts a file saved in the RDS format to the qs2 format.

Usage

rds_to_qs(input_file, output_file, compress_level = 3)

Arguments

input_file	The RDS file to convert.
output_file	The qs2 file to write.
compress_level	The zstd compression level to use when writing the qs2 file. See the qs_save help file for more details on this parameter.

Details

rds_to_qs() currently supports only gzip-compressed RDS input files. Files that are uncompressed or use another compression format are rejected.

The shuffle parameter is currently not supported when converting from RDS to qs2.

Value

No value is returned. The converted file is written to disk.

Examples

qs_tmp <- tempfile(fileext = ".qs2")
rds_tmp <- tempfile(fileext = ".RDS")

x <- runif(1e6)
saveRDS(x, rds_tmp, compress = "gzip")
rds_to_qs(input_file = rds_tmp, output_file = qs_tmp)
x2 <- qs_read(qs_tmp, validate_checksum = TRUE)
stopifnot(identical(x, x2))
