qs_deserialize

Source: R/qx_functions.R
qs_deserialize.Rd

Deserializes a raw vector to an object using the qs2 format.

Usage

qs_deserialize(input,
         validate_checksum = qopt("validate_checksum"),
         nthreads = qopt("nthreads"))

Arguments

input

The raw vector to deserialize.

validate_checksum

If TRUE, validate checksum before deserialization and error on mismatch (or missing checksum). If FALSE, checksum is computed during read and mismatches (or missing checksum) produce a warning after reading (the initial value is FALSE).

nthreads

The number of threads to use when reading data (the initial value is 1L). When TBB is not available, values greater than 1 emit a warning and fall back to 1.

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 <- qs_serialize(x)
x2 <- qs_deserialize(xserialized)
identical(x, x2) # returns TRUE
#> [1] TRUE
