In reply to @.bobbbob "this is a specific": depends of usecase
stream's (like faststreams) are roundly fast as just reading file to string,
since you always can use memfile input or whatever it called (don't remember
how, but remember that's exists). streams usually slow in cases where
allocations happens — nothing more. also streams eat very small memory for big
files, like you wanna parse java files? stream's better than just file to
string, and another examples like parsing archives, the way zippy (guzba
library) do it can be used with memfile stream
