Using Config Files

Using the Serde library to read TOML config files.

Example Configs

Config 1 does not have the maybe_matrix field.

a_list = ["woof", "woof", "WOOF"]
a_string = "raaaarrrrrrr"
a_int = 1728
a_float = 3.14
maybe_string = "string was here"
maybe_ints = [3, 42, 180, 360]

Config 2 does not have maybe_string or maybe_ints. It also has a field not present in the Rust struct, maybe.

a_list = ["meow", "meow", "MEOW"]
a_string = "weeeee"
a_int = 42
a_float = 2.78
maybe = "AWW YEAH"
maybe_matrix = [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]]

Output

$ cargo run
...

- a string: raaaarrrrrrr
- a int: 1728
- a float: 3.14

- maybe ints: [3, 42, 180, 360]
- maybe matrix: [[]]
 
CONVERT:
- maybe string: STRING WAS HERE
- maybe ints: 3, 42, 180, 360
- maybe matrix: none
