I couldn't find a tool that generates uuid's of various formats conveniently and programatically over the cli and rUUID was born. Necessity is the mother of "I can't find it, I'll make it".
This crate only depends on
Since for uuid version 6, 7 and 8 the
uuid crate needs to be compiled with
RUSTFLAGS="--cfg uuid_unstable". For you, this means when you install
ruuid, you need to pass
that unless you want compilation errors. For example:
RUSTFLAGS="--cfg uuid_unstable" cargo install ruuid
RUSTFLAGS="--cfg uuid_unstable" cargo install --git https://github.com/westernwontons/ruuid
There are subcommands for each type of supported uuid's. Any uuid formats supported by
uuid are supported by
rUUID as well.
For example, to generate a UUID_V1:
To generate a version 1 UUID with the braced format:
ruuid v1 -b
You can pass a number to tell
ruuid how many UUIDs you want generated:
ruuid v1 3
The default number of UUIDs generated is 1.
The following UUIDs are supported:
- version 1
- version 3
- version 4
- version 5
- version 6
- version 7
- version 8
Version 1, 3, 5, 6 and 8 need some random bytes to be generated, namely 6 pieces of
u8 (except for version 8 which needs 16
These are generated with the help of the rand crate. Honestly I have no ideas whether is sufficient, if it's not, let me know.
Version 3 and 5 implicitly use the DNS namespace. I don't know whether it would be preferable to have that configurable. It's static for know. If you'd like that changed, let me know.
