How to get more recent version of https://docs.rs/nix/0.17.0/nix/ifaddrs/ when a new nix is released. Use case: A stable URL like https://docs.rs/nix/lastest/nix/ifaddrs/
@1000teslas_gitlab None of Nix's types currently support serde, but it would be a reasonable thing to add.
I want to use nix::mount::mount() to replace with libc::mount(). Now I have the followed code :
libc::mount(ptr::null(), path.as_ptr(), ptr::null(), libc:: MS_SLAVE, ptr::null())I just want to know how to replace the ptr::null() in nix library, I try to use 'None' to do it, but failed. Please help me, thanks.
The error is :
``

Whoa, @wca ! I didn't notice your username when you asked that question. The answer is, yes, there are a few places that already use
libc::syscall on Linux. fcntl::copy_file_range and unistd::gettid, for example.
hi, i have published this crate https://crates.io/crates/git-gamble and i would like to use it with Nix
but i don't really know how to do that, can you help me please ?
{ pkgs ? import <nixpkgs> {} }:
pkgs.mkShell {
buildInputs = with pkgs; [
git-gamble
];
}nixpkgs)
is not the topic of the channel ?
may i suggest to put the link of the package in the subject of this room
hey folks, I'm looking to get involved with this project and would love to start where ever help is needed
hi @asomers
Oh i dont have a project yet I just stumbled on nix because I love linux systems internals and definitely love rust
I'm a sre by trade
If you want to chip in , there are a bunch of half-finished PRs and unaddressed issues.
@asomers: I decided to patch this nix-rust/nix#1202 but it seems like i dont have write perms to push my branch up ?
@asomers: ^^
