Struct Watchlist 

pub struct Watchlist {
    pub domains: Vec<String>,
}

Persistent list of domains to monitor.

Fields

domains: Vec<String>

Implementations

impl Watchlist

pub fn path() -> Option<PathBuf>

Returns the path to the watchlist file (~/.seer/watchlist.toml).

pub fn load() -> Self

Loads the watchlist from disk, returning an empty list on any failure.

When the file exists but fails to parse, it is renamed to <path>.corrupt (preserving the user’s data for recovery/forensics) and a warning is logged — previously the file was silently overwritten on the next save, dropping the user’s watchlist.

pub fn save(&self) -> Result<()>

Persists the watchlist to disk via write-and-rename so a crash mid-write cannot leave the file truncated (the next load() would see corrupt TOML and silently fall back to the default empty watchlist, losing the user’s domains). Mirrors LookupHistory::save.

The temp filename is suffixed with the current PID so two concurrent seer processes don’t write to the same intermediate path and race each other’s renames.

Concurrency

As with crate::history::LookupHistory::save, the write is atomic but the load → add/remove → save cycle is not cross-process locked: two concurrent writers can lose one side’s add/remove (last-writer-wins). No corruption occurs. A cross-process advisory lock would close the window; it is omitted to avoid a new dependency for a low-frequency edge case.

pub fn add(&mut self, domain: &str) -> Result<bool>

Adds a domain to the watchlist. Returns Ok(true) if the domain was newly added.

pub fn remove(&mut self, domain: &str) -> bool

Removes a domain from the watchlist. Returns true if the domain was present.
