Struct ContactsCache 

pub struct ContactsCache {
    pub by_email: HashMap<String, Contact>,
    pub last_refreshed: Option<DateTime<Utc>>,
}

JSON-backed contact cache. Keyed by lowercase email.

Fields

by_email: HashMap<String, Contact>

last_refreshed: Option<DateTime<Utc>>

Implementations

impl ContactsCache

pub fn default_path() -> Result<PathBuf, CoreError>

${XDG_CACHE_HOME:-~/.cache}/pidge/contacts.json.

pub fn load() -> Result<Self, CoreError>

pub fn load_from(path: &Path) -> Result<Self, CoreError>

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

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

pub fn upsert( &mut self, email: &str, display_name: &str, seen_at: DateTime<Utc>, source: ContactSource, )

Insert one observation. Email is lowercased; display name is only applied when non-empty (we never overwrite a known name with ""). last_seen advances to the later of the existing and new values so out-of-order refreshes converge to the right state.

pub fn mark_refreshed(&mut self, at: DateTime<Utc>)
