Struct TodoList 

pub struct TodoList {
    pub name: String,
    pub list: Vec<Todo>,
}

Simple todo list structure.

Todos can be grouped together in so called todo lists (as in the real world). Therefore, the TodoList struct can be used. It’s a simple data structure that holds a number of Todo items and offers all basic functions for managing them.

Fields

name: String

Name of the todo list.

list: Vec<Todo>

The actual vector of Todo items.

Implementations

impl TodoList

pub fn new(name: &str) -> TodoList

Create a new list with the given name.

Example

let mut list = TodoList::new("important");

pub fn add(&mut self, new_todo: Todo)

Add a new todo to the list.

Example

list.add(Todo::new(0,"A first important todo", None));

pub fn contains_id(&self, id: u32) -> TdoResult<usize>

Check if the list contains a todo with the given ID.

This function returns a TdoResult, wich will contion a TodoError::NotInList if the list does not contain any todo with the given ID or the position in the list.

pub fn done_id(&mut self, id: u32) -> TdoResult<()>

Mark a todo from the list with the given ID as done.

This function returns a TdoResult, which will contain a TodoError::NotInList if the list does not contain any todo with the given ID.

pub fn remove_id(&mut self, id: u32) -> TdoResult<Todo>

Remove a todo with the given ID from the list.

This function returns a TdoResult, which will contain the removed Todo itself or a TodoError::NotInList if the list does not contain any todo with the given id.

pub fn list_undone(&self) -> Vec<Todo>

Search for all undone todos in the list.

Returns a vector of all undone todos.

pub fn clean(&mut self)

Remove all done todos from the list.

pub fn pop_id(&mut self, todo_id: u32) -> TdoResult<Todo>

Remove a todo with a specific ID from the list.

pub fn insert_todo(&mut self, todo: Todo)

Insert an existing todo into the list, preserving the ordering of the internal list.

Trait Implementations

impl Clone for TodoList

fn clone(&self) -> TodoList

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TodoList

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TodoList

Instanciates a default TodoList. This function is invoked when a Tdo container structure is instanciated.

fn default() -> TodoList

Returns the “default value” for a type.

impl Deserialize for TodoList

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer,

Deserialize this value from the given Serde deserializer.

impl Serialize for TodoList

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
