Struct TodoState 

pub struct TodoState {
    pub items: Vec<TodoItem>,
    /* private fields */
}

Shared TODO state that can be persisted.

Fields

items: Vec<TodoItem>

The list of TODO items.

Implementations

impl TodoState

pub const fn new() -> Self

Creates a new empty TODO state.

pub const fn with_storage(path: PathBuf) -> Self

Creates a new TODO state with persistence.

pub fn set_storage_path(&mut self, path: PathBuf)

Sets the storage path for persistence.

pub async fn load(&mut self) -> Result<()>

Loads todos from storage if path is set.

Errors

Returns an error if the file cannot be read or parsed.

pub async fn save(&self) -> Result<()>

Saves todos to storage if path is set.

The write is atomic: the JSON is written to a uniquely-named temp file in the same directory and then renamed over the target (atomic on POSIX). A crash or a cancelled future mid-write can therefore never leave a truncated/invalid file in place, which load would otherwise fail to parse permanently.

Errors

Returns an error if the file cannot be written or renamed into place.

pub fn set_items(&mut self, items: Vec<TodoItem>)

Replaces the entire TODO list.

pub fn add(&mut self, item: TodoItem)

Adds a new TODO item.

pub fn count_by_status(&self) -> (usize, usize, usize)

Returns the count of items by status.

pub fn current_task(&self) -> Option<&TodoItem>

Returns the currently in-progress item, if any.

pub fn format_display(&self) -> String

Formats the TODO list for display.

pub const fn is_empty(&self) -> bool

Returns true if there are no items.

pub const fn len(&self) -> usize

Returns the number of items.

Trait Implementations
