Generating Universally Unique Identificators
Description
Provides functions to generating a vector of Universally Unique Identifiers (UUID) using the implementation from the Boost C++ library. Supports random (version 4), name (version 5) and time-based (version 7) UUIDs. UUIDs generation is parallelized by OpenMP.

Generate UUIDs Version 5
Description
Function generates name-based uuid is derived from content in a namespace. A uuid with identical content shall yield the same uuid. Hashing algorithm is SHA1.
Usage
uuid_generate_name(x, ns = "x500dn")
Arguments
x |
Character vector. |
ns |
Namespace string. Allowed values: dns, url, oid, x500dn. |
Value
Character vector with UUIDs.
Note
This function generates valid uuids for the NA and empty strings.

Examples
# generate name UUIDs
uuid_generate_name(c("one", "two"))
Generates Nil UUIDs
Description
Function generates nil uuids.
Usage
uuid_generate_nil(n = 1L)
Arguments
n |
Number of generated UUIDs. |
Value
Character vector with UUIDs.

Examples
# generate nil UUIDs
uuid_generate_nil(2)
Generate UUIDs Version 4
Description
Function generates uuids using operating system provided entropy.
Usage
uuid_generate_random(n = 1L)
Arguments
n |
Number of generated UUIDs. |
Value
Character vector with UUIDs.

Examples
# generate random UUIDs
uuid_generate_random(2)
Generate UUIDs Version 7
Description
This function generates time-based uuids using operating system provided entropy. Note that this requires Boost 1.86 or later.
Usage
uuid_generate_time(n = 1L)
Arguments
n |
Number of generated UUIDs. |
Value
Character vector with UUIDs generated under specification v7.
References

Examples
# generate random UUIDs
uuid_generate_time(2)
Validate UUIDs
Description
Function validates uuids.
Usage
uuid_validate(x)
Arguments
x |
Character vector. |
Value
Logical vector.
Examples
# validate UUIDs
uuid_validate(uuid_generate_random(2))
uuid_validate(uuid_generate_nil(2))
uuid_validate(uuid_generate_name(c("one", "two")))
uuid_validate(c("a", ""))
