Trait Implementations

impl Default for MemoryReminderStore

fn default() -> Self

Returns the “default value” for a type.

impl ReminderStore for MemoryReminderStore

fn save(&self, reminder: &Reminder) -> Result<(), ReminderError>

Persist a new reminder. The id field is already populated by CreateReminder::into_reminder().

fn get(&self, id: &str) -> Result<Option<Reminder>, ReminderError>

Retrieve a reminder by ID.

fn update(&self, reminder: &Reminder) -> Result<(), ReminderError>

Overwrite the full reminder record (used after in-place mutations).

fn update_if_unchanged( &self, expected: &Reminder, new: &Reminder, ) -> Result<bool, ReminderError>

Write new only if the stored reminder still equals expected (what the caller read). Returns Ok(false) when it changed in between; the caller re-reads and re-applies. Every lifecycle method is a read-modify-write of the whole record, and an unconditional update silently reverted a concurrent change (a cancel, snooze, or execution record) while both calls returned Ok.

fn delete(&self, id: &str) -> Result<bool, ReminderError>

Delete a reminder permanently (hard delete, for admin use only; normal cancellation uses update with status: Cancelled).

fn list(&self, filter: &ReminderFilter) -> Result<Vec<Reminder>, ReminderError>

Return all reminders matching filter, ordered by priority then due_at ascending.
