returning the result of a `let` binding from a block

this expression creates a reference which is immediately dereferenced by the compiler

unsafe function's docs are missing a `# Safety` section

useless conversion to the same type: `std::collections::hash_map::Keys<'_, dora_core::config::DataId, (usize, std::collections::VecDeque<event_stream::thread::EventItem>)>`

this `if` has identical blocks

this expression creates a reference which is immediately dereferenced by the compiler

this expression creates a reference which is immediately dereferenced by the compiler

this `if` statement can be collapsed

this function has too many arguments (8/7)
