Struct GuardrailContext 

pub struct GuardrailContext {
    pub db_lock_path: PathBuf,
    pub pacman_cache_dir: PathBuf,
    pub sync_db_dir: PathBuf,
    pub proc_dir: PathBuf,
    pub min_free_mib: u64,
    pub stale_sync_days: u64,
}

Filesystem locations and thresholds consulted by the guardrail checks.

Details: Injectable so tests can point the checks at temporary directories.

Fields

db_lock_path: PathBuf

Path of the pacman database lock file.

pacman_cache_dir: PathBuf

Pacman package cache directory (download target for installs/updates).

sync_db_dir: PathBuf

Directory holding the pacman sync databases (*.db).

proc_dir: PathBuf

Root of the /proc filesystem used to detect running package managers.

min_free_mib: u64

Minimum free space (MiB) below which a warning is raised.

stale_sync_days: u64

Age in days after which the sync databases are considered stale.

Trait Implementations

impl Default for GuardrailContext

fn default() -> Self

What: Build the standard Arch Linux locations with default thresholds.

Inputs:

• None.

Output:

• Context pointing at /var/lib/pacman, /var/cache/pacman/pkg, and /proc, with a 1 GiB free-space minimum and a 14-day staleness window.

Details:

• Paths intentionally match pacman defaults; systems with a relocated DBPath can construct the context manually.
