Datastructures for Elixir
This is a collection of protocols, implementations and wrappers to work with datastructures.
The stdlib of Elixir right now is very poor and every now so you end up using the Erlang libraries, which have different APIs from the rest of idiomatic Elixir, and on top of that they lose all the protocol goodies.
Protocols
Sequence
first/1
 returns the first element in the sequence or nilnext/1
 returns a new sequence with the first element removed or nil
Counted
count
 returns the length of the structure
Emptyable
empty?/1
 checks if the structure is emptyclear/1
 returns an empty structure
Reducible
reduce/3
 reduces the structures
Sequenceable
to_sequence/1
 converts the structure to a sequence
Listable
to_list/1
 converts the structure to a list
Peekable
peek/1
 peeks and returns nil if the structure emptypeek/2
 peeks and returns the default value if the structure emptypeek!/1
 peeks and raises if the structure is empty
Reversible
reverse/1
 reverses the structure
Contains
contains?/2
 checks if the structure contains the passed value
Queue
enq/2
 enqueues a value in the structuredeq/1
 dequeues a value from the structure, returning nil if it's emptydeq/2
 dequeues a value from the structure, returning the default if it's emptydeq!/1
 dequeues a value from the structure, raising if it's empty
Stack
push/2
 pushes a value in the structurepop/1
 pops a value from the structure, returning nil if it's emptypop/2
 pops a value from the structure, returning the default if it's emptypop!/1
 pops a value from the structure, raising if it's empty
Set
add/2
 adds a value to the structuredelete/2
 deletes a value from the structureunion/2
 returns the union of the two structuresintersection/2
 returns the intersection of the two structuressubset?/2
 checks if the two structures are subsetsdisjoint?/2
 checks if the two structures are disjoint
Dictionary
get/2
 gets a value from the structure by its key, returning nil if there isn't oneget/3
 gets a value from the structure by its key, returning the default if there isn't oneget!/2
 gets a value from the structure by its key, raising if there isn't oneput/3
 puts a value in the structure with its keydelete/2

You're awful, those names are long
I know right? Just use alias
.
alias Data.Set, as: S
alias Data.Set.BalancedTree, as: SBT
SBT.new > S.add(23) > S.add(42) # => #Set<[23,42]>
