Instructions

---

add

---

for

Iterates over set elements

Expressions

---

add

---

remove

---

update

---

contains

Tests if set contains an elements

---

length

---

make_set

Makes set from literal

List

A list is a container of elements, where elements are in the order they are added.

Instructions

---

prepend

Adds first element to list

---

reverse

---

concat

---

for

---

match with

Controls execution flow based on list structure

Expressions

---

contains

Tests if an element is in list

---

length

Number of elements in list

---

prepend

---

reverse

---

concat

---

nth

---

head

---

tail

---

map

---

make_list

---

match with

Controls expression value based on list structure

Map

A map associates one key to one value.

Besides basic map there are two other maps type:

• big_map to store large collections of non iterable key-value pairs
• iterable_big_map for a large iterable collection of key-value pairs

Below is the list of map-related instructions and operators.

Note that for instruction and length builtin are not available for big_map type.

Instructions

---

put

Associates key to value

---

remove

---

update

Adds key or removes key from map

---

for

Iterates over map's key-value pairs

Expressions

---

[]

Returns value associated to key in map

---

put

Associates key to value

---

remove

Removes key from map

---

update

Adds key or removes key from map

---

contains

Tests if a key is in map

---

length

Number of keys in map

---

make_map

Makes map from literal

---

map
