Structs

Structs are similar to tuples with named field values of arbitrary pre-declared types.

Fig 1:

var myStruct: struct {x: int, y: int} = {x = 1, y = 2};
print(myStruct);

Output:

{x = 1, y = 2}

Field Access

Struct field values can be directly accessed using "dot-notation" as below:

Fig 2:

var myStruct: struct {x: int, y: int} = {x = 1, y = 2};
print(myStruct.x);
print(myStruct.y);

Output:

1
2

Mutable Structs

Just like any other builtin collection type, a Claro struct may be declared mutable using the mut keyword when declaring a variable or initializing the value. You may then update element values at will as long as the initial type declaration for each element is honored.

Fig 3:

var myStruct = mut {name = "Jason", age = 29};  # <-- Omitting optional type annotation.
print(myStruct);

myStruct.name = "Claro";  # <-- Mutation happens here.
myStruct.age = 3;         # <-- Mutation happens here.
print(myStruct);

Output:

mut {name = Jason, age = 29}
mut {name = Claro, age = 3}
