Struct BulkWriter 

Source 
pub struct BulkWriter<'c> { /* private fields */ }
Expand description

A batch of track writes held in one transaction. Mirrors Db::upsert_track / replace_tags / upsert_art / set_track_art, but executes on a single caller-held transaction so a whole batch commits with one fsync.
