Required Methods

fn count<'q>( &'q mut self, kind: Option<EntryKind>, category: Option<&'q str>, tag_filter: Option<TagFilter>, ) -> BoxFuture<'q, Result<i64, Error>>

Count the number of matching records in the store

fn fetch<'q>( &'q mut self, kind: EntryKind, category: &'q str, name: &'q str, for_update: bool, ) -> BoxFuture<'q, Result<Option<Entry>, Error>>

Fetch a single record from the store by category and name

fn fetch_all<'q>( &'q mut self, kind: Option<EntryKind>, category: Option<&'q str>, tag_filter: Option<TagFilter>, limit: Option<i64>, order_by: Option<OrderBy>, descending: bool, for_update: bool, ) -> BoxFuture<'q, Result<Vec<Entry>, Error>>

Fetch all matching records from the store

fn remove_all<'q>( &'q mut self, kind: Option<EntryKind>, category: Option<&'q str>, tag_filter: Option<TagFilter>, ) -> BoxFuture<'q, Result<i64, Error>>

Remove all matching records from the store

fn update<'q>( &'q mut self, kind: EntryKind, operation: EntryOperation, category: &'q str, name: &'q str, value: Option<&'q [u8]>, tags: Option<&'q [EntryTag]>, expiry_ms: Option<i64>, ) -> BoxFuture<'q, Result<(), Error>>

Insert or replace a record in the store

fn ping(&mut self) -> BoxFuture<'_, Result<(), Error>>

Test the connection to the store

fn close(&mut self, commit: bool) -> BoxFuture<'_, Result<(), Error>>

Close the current store session

Provided Methods

fn import_scan<'q>( &'q mut self, scan: Scan<'q, Entry>, ) -> BoxFuture<'q, Result<(), Error>>

Insert scan results from another profile or store

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
