# Vectors
|
|
# - Must have fixed size and type
|
|
|
|
# Lists
|
|
# - Variable size, variable type
|
|
|
|
# Define a variable of type int:
|
|
n: int = 3
|
|
|
|
# Define v as a 3-dimensional vector of integers:
|
|
v: int<3> = <4, 5, 6>
|
|
|
|
# Define l as list of length 3:
|
|
l: [3] = [1, 2, "These can be any type at all"]
|
|
# This would also work, as length values for lists are optional (and mutable),
|
|
# unlike vectors:
|
|
l: [] = [1, 2, "whatever"]
|
|
# This is also the same, being more explicit about the any type:
|
|
l: any[] = [1, 2, "whatever"]
|
|
# This must be a list of integers, however:
|
|
l: int[] = [1, 2, 3]
|
|
|
|
# Define a list of either integers or strings:
|
|
l: union(int, str)[] = ["hello", 4, "world"]
|
|
# union() is a complex type generator; "returns" a union of the int and str types.
|
|
|
|
# Use vectors wherever possible, as they are much faster than lists.
|
|
|
|
# Matrix
|
|
# - Must have a fixed size and type (just like vectors)
|
|
m: int<2, 2> = <<0, 1>, <2, 3>>
|
|
# Can also be written as
|
|
m: int<2, 2> = <<0, 1, 2, 3>>
|
|
# When using this syntax, will fill remaining space with default value of type
|
|
# to make data rectangular. E.g., to fill a 2 x 2 matrix with 0:
|
|
m: int<2, 2> = <<>>
|
|
|
|
# To define custom data types, e.g. structs:
|
|
typedef(Vec2, struct( a: int, b: int ))
|
|
vector_two: Vec2 = Vec2(2, 3)
|
|
|
|
typedef(IntOrStr, union(str, int))
|
|
one: IntOrStr = 1
|
|
alsoOne: IntOrStr = "one"
|
|
|
|
# To define custom data types with type arguments:
|
|
typedef(Vec1Of(T), T<1>)
|
|
hello: Vec1Of(str) = <"Hello">
