Struct InvokingUser 

pub struct InvokingUser { /* private fields */ }

The account that launched ND300, even when the process is elevated by sudo.

Implementations

impl InvokingUser

pub fn detect() -> Result<Self>

Resolve the invoking account from numeric sudo metadata and the passwd database. Without a valid sudo UID, this resolves the effective user.

pub fn uid(&self) -> uid_t

pub fn gid(&self) -> gid_t

pub fn username(&self) -> &str

pub fn home(&self) -> &Path

pub fn cargo_home(&self) -> PathBuf

Cargo home for the invoking account. An explicit CARGO_HOME is honored only when ND300 is not crossing from root to another user; sudo-inherited root environment variables must never redirect a user update into /var/root.

pub fn is_different_from_effective_user(&self) -> bool

pub fn configure_command(&self, command: &mut Command)

Run a user-scoped child as the invoking account rather than root.

pub fn write_private_atomic(&self, path: &Path, bytes: &[u8]) -> Result<()>

Write a private file through a same-directory temporary file, then atomically rename it into place. The file is mode 0600 and is owned by the invoking user even when ND300 itself is root.

pub fn ensure_directory(&self, path: &Path) -> Result<()>

Ensure a user-scoped directory exists and belongs to the invoking user.

pub fn ensure_directory_beneath_home(&self, path: &Path) -> Result<()>

Validate and create a report directory strictly beneath the passwd home without following a symlink out of that tree.
