xxhash_file {xxhashlite}

Calculate the hash of a file

Description

Calculate the hash of a file

Usage

xxhash_file(file, algo = "xxh128", as_raw = FALSE)

Arguments

file

filename

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

filename <- system.file('DESCRIPTION', package = 'base', mustWork = TRUE)
xxhash_file(filename)
