Fields

program: CString

args: Vec<CString>

argv: Argv

Exactly what will be passed to execvp.

First element is a pointer to program, followed by pointers to args, followed by a null. Be careful when modifying program or args to properly update this as well.

env: CommandEnv

program_kind: ProgramKind

cwd: Option<CString>

uid: Option<uid_t>

gid: Option<gid_t>

saw_nul: bool

closures: Vec<Box<dyn FnMut() -> Result<()> + Send + Sync>>

groups: Option<Box<[gid_t]>>

stdin: Option<Stdio>

stdout: Option<Stdio>

stderr: Option<Stdio>

create_pidfd: bool

pgroup: Option<pid_t>
