Struct Storage

pub struct Storage { /* private fields */ }

Storage for meal data.

Implementations

impl Storage

pub fn open(path: &str) -> Result<Self>

Opens a storage in the given path. Given a path to a non-existing file, this will try to create a new storage in that path and then open it.

Example:

use libmrot::Storage;

let storage = Storage::open("./path/to/my_storage").unwrap();

For testing purposes the special path :memory: gives access to an in-memory storage which will live as long as the instance of this struct.

Example:

use libmrot::Storage;

let test_storage = Storage::open(":memory:").unwrap();

pub fn add_meal_on_dates(&self, meal: &str, dates: &Vec<String>) -> Result<()>

Adds a meal on the given dates to the storage.

pub fn when(&self, meal: &str) -> Result<Vec<NaiveDate>>

Show on what dates a meal was recorded.

pub fn show(&self, date_range: &str) -> Result<Vec<MealRecord>>

Show what meals were recorded in the given date range.

pub fn what( &self, number: usize, ignore: &Vec<String>, look_ahead: &Vec<NaiveDate>, ) -> Result<Vec<MealRecord>>

Suggest meals to cook. Returns MealRecords of the suggested meals and the last dates when they were cooked. Ignores the meals in the ignore vector and meals recorded on the dates in the look_ahead vector.
