is there a standard of when to use higher order functions vs interfaces with one method?

[Andrew Gazelka]

maybe it is just me, but val permissions = HashSet<(CommandSender) -> Boolean>() seems slightly jank

[Andrew Gazelka]

also HOF don't really specify what the function is doing whereas interfaces do

[Andrew Gazelka]

is having two functions, one accepting an interface and one accepting a HOF redundant? (HOF would be wrapped in interface)

[Shawn]

conversely, interfaces generally don’t tell you what the function takes and returns

[Shawn]

if you find yourself writing this type out a lot, maybe a typealias is a good middle ground?

[Andrew Gazelka]

yeah, probably

honestly, seems like HOF is often preferable even in case of interfaces with multiple functions. It's more granular and flexible this way. A good example would be TextWatcher on Andorid that got splitted into separate lambdas in ktx library.
