In the year of our lord 2024 we should not be writing for loops
for standard operations. Here we introduce named slice operations
not found in the golang slices package. Note all these functions
are pure.
In this commit, we add two new methods that simplify usage of an
handling a value wrapped in an Option. Thes methods allow a caller to
force the nil/None check up front, and either obtain the value, or fail
the current execution or test.
This should replace most usages of `UnsafeFromSome` where ever used
today.
This builds on the concurrent queue to create a generic way to allow
goroutines to pub/sub information. An example includes being notified
each time a state machine is able to carry out a new state transition.
In this commit, we make a new sub-module from the `fn` package. This
lets other projects use it w/o pulling in all of lnd, and also other
sub-packages within lnd.
We also add a temp replace directive for new module. We'll remove this
once we tag the final version.
We start with a simple Map function that can be useful for transforming
objects on the fly.
We may want to eventually make this Taro pakage into a module so we can
just have everything in one place:
