tmp <- tempfile()
writer <- BinaryWriter(tmp, byte_offset = 0L,
                      data_type = "DOUBLE", bytes_per_element = 8L)
write_elements(writer, rnorm(100))
close(writer)

# Read the data back
reader <- BinaryReader(tmp, byte_offset = 0L,
                      data_type = "DOUBLE", bytes_per_element = 8L)
data <- read_elements(reader, 100)
#> Warning: incomplete string at end of file has been discarded
close(reader)
