Create Collector and Category Struct

[ngreese]

Make structs, enums, and implementations to enable flag usage to specify what data to get.

Category/Metrics Enum

enum Category {
    cpu,
    net,
    du,
    ...
}

Collector struct/impl

struct Collector {
    categories: Vec<Category>,
}

impl Collector {
    pub fn collect() -> serde_json::Value {}
    fn all_categories() -> &Self {} // Category::*
    fn set_categories(selected: Vec<Category>) -> &Self {} // Vec<Category> [cpu,net]
}

CLI example

./tinyd // calls all_categories()
./tinyd --all //calls all_categories()
./tinyd --collect "a,b,c" // (or --categories, --types?) calls set_categories([a,b,c])

[ngreese]

for all the category enums also make them structs with a trait and impl @ngreese

enum Category {
    CpuFreq(CpuFreq),
    ...
}

trait Category {
    fn collect(&self) -> serde_json::Value;
}

impl Category for CpuFreq {
    fn get(&self) -> serde_json::Value {
        get_cpu_freq()
    }
}

@ngreese are you planning on working on this? collector.rs looks very different now.

[ngreese]

Yes I was just waiting for your changes to sync them

[avakianssion]

great, I will start some basic unit tests with the expectation that they will break with your changes.

Make sure to add some Miri tests too to check if there is any unexpected behavior in the way we use some of the crates
