xxhash_raw: Calculate the hash of a raw vector or string

In xxhashlite: Extremely Fast Hashing of R Objects, Raw Data and Files using 'xxHash' Algorithms

Calculate the hash of a raw vector or string

Description

This performs a hash of the raw bytes - not of the serialized representation.

Usage

xxhash_raw(vec, algo = "xxh128", as_raw = FALSE)

Arguments

vec	raw vector or single character string
algo	Select the specific xxhash algorithm. Default: 'xxh128'. (the latest algorithm in the xxhash family) Valid values: 'xxh32', 'xxh64', 'xxh128', 'xxh3'
as_raw	Return the hash as a raw vector of bytes instead of string? Default: FALSE. If TRUE, then the raw bytes are returned in big-endian order - which is what xxHash considers the canonical form.

Value

String representation of hash. If as_raw = TRUE then a raw vector is returned instead.

Examples

vec <- "hello"
xxhash_raw(vec)
vec <- as.raw(c(0x01, 0x02, 0x99))
xxhash_raw(vec)
