Description

Fast, portable, high quality UUID implementation

Reference: see RFC 4122 - (UUID) URN Namespace.

Data Types

uuid()

uuid() = <<_:128>>

v1()

v1() = uuid()

v3()

v3() = uuid()

v4()

v4() = uuid()

v5()

v5() = uuid()

Function Index

check/1	Check whether the argument is a valid UUID or not.
to_str/1	Convert a raw UUID binary value to a (printable) string.
urn/0	Generates a Uniform Resource Name (URN) - RFC 4122.
v1/0	Generate a Version 1 (MAC address) UUID.
v3/1	Generate a Version 3 (MD5 hash) UUID.
v4/0	Generate a Version 4 (random) UUID.
v5/1	Generate a Version 5 (SHA-1 hash) UUID.

Function Details

check/1

check(UUID::uuid()) -> {true, v1 | v3 | v4 | v5} | false

Check whether the argument is a valid UUID or not.

to_str/1

to_str(UUID::uuid()) -> [byte()]

Convert a raw UUID binary value to a (printable) string.

urn/0

urn() -> binary()

Generates a Uniform Resource Name (URN) - RFC 4122.

Examples:

"urn:uuid:344f2478-7aeb-11e1-b946-1acd00000029"
"urn:uuid:3c4e5086-7aeb-11e1-e99a-1acd00000029"
"urn:uuid:4042c21b-d898-43f0-9c95-b50da2d1aa42"

This call garantees to always makes a new identifier.

v1/0

v1() -> v1()

Generate a Version 1 (MAC address) UUID.

See Universally unique identifier - V1 for more information.

v3/1

v3(Any::[any()]) -> v3()

Generate a Version 3 (MD5 hash) UUID.

See Universally unique identifier - V3 for more information.

v4/0

v4() -> v4()

Generate a Version 4 (random) UUID.

See Universally unique identifier - V4 for more information.

v5/1

v5(Any::any()) -> v5()

Generate a Version 5 (SHA-1 hash) UUID.

See Universally unique identifier - V5 for more information.
