# Structs
|
||
|
|
|
||
|
|
In Tomo, you can define your own structs, which hold members with arbitrary
|
||
|
|
types that can be accessed by fields:
|
||
|
|
|
||
|
|
```tomo
|
||
|
|
struct Foo(name:Text, age:Int)
|
||
|
|
...
|
||
|
|
>> my_foo := Foo("Bob", age=10)
|
||
|
|
= Foo(name="Bob", age=10)
|
||
|
|
>> my_foo.name
|
||
|
|
= "Bob"
|
||
|
|
```
|
||
|
|
|
||
|
|
Structs are value types and comparisons on them operate on the member values
|
||
|
|
one after the other.
|
||
|
|
|
||
|
|
## Namespaces
|
||
|
|
|
||
|
|
Structs can define their own methods that can be called with a `:` or different
|
||
|
|
values that are stored on the type itself.
|
||
|
|
|
||
|
|
```tomo
|
||
|
|
struct Foo(name:Text, age:Int):
|
||
|
|
oldest := Foo("Methuselah", 969)
|
||
|
|
|
||
|
|
func greet(f:Foo):
|
||
|
|
say("Hi my name is $f.name and I am $f.age years old!")
|
||
|
|
|
||
|
|
func get_older(f:&Foo):
|
||
|
|
f.age += 1
|
||
|
|
...
|
||
|
|
my_foo := Foo("Alice", 28)
|
||
|
|
my_foo:greet()
|
||
|
|
my_foo:get_older()
|
||
|
|
```
|
||
|
|
|
||
|
|
Method calls work when the first argument is the struct type or a pointer to
|
||
|
|
the struct type.
