In qs2: Efficient Serialization of R Objects

qd_deserialize

Description

Deserializes a raw vector to an object using the qdata format.

Usage

qd_deserialize(input,
         use_alt_rep = qopt("use_alt_rep"),
         validate_checksum = qopt("validate_checksum"),
         nthreads = qopt("nthreads"))

Arguments

input	The raw vector to deserialize.
use_alt_rep	Use ALTREP when reading in string data (the initial value is FALSE).
validate_checksum	Whether to validate the stored checksum in the file (the initial value is FALSE).
nthreads	The number of threads to use when reading data (the initial value is 1L).

Value

The deserialized object.

Examples

x <- data.frame(int = sample(1e3, replace=TRUE),
         num = rnorm(1e3),
         char = sample(state.name, 1e3, replace=TRUE),
         stringsAsFactors = FALSE)
xserialized <- qd_serialize(x)
x2 <- qd_deserialize(xserialized)
identical(x, x2) # returns TRUE
