Trait holochain_types::db::ReadManager

pub trait ReadManager<'e> {
    // Required methods
    fn with_reader<E, R, F>(&'e mut self, f: F) -> Result<R, E>
       where E: From<DatabaseError>,
             F: 'e + FnOnce(Transaction<'_>) -> Result<R, E>;
    fn with_reader_test<R, F>(&'e mut self, f: F) -> R
       where F: 'e + FnOnce(Transaction<'_>) -> R;
}

Implementors are able to create a new read-only DB transaction

Required Methods

fn with_reader<E, R, F>(&'e mut self, f: F) -> Result<R, E>where E: From<DatabaseError>, F: 'e + FnOnce(Transaction<'_>) -> Result<R, E>,

Run a closure, passing in a new read-only transaction

fn with_reader_test<R, F>(&'e mut self, f: F) -> Rwhere F: 'e + FnOnce(Transaction<'_>) -> R,

Same as with_reader, but with no Results: everything gets unwrapped
