Enum TodoStatus 

pub enum TodoStatus {
    Pending,
    Done,
    Cancelled,
}

Status of a TODO item.

TODOs progress through different states during their lifecycle. Reopening a completed or cancelled TODO (transition back to Pending) is not allowed; add a new TODO instead.

Variants

Pending

TODO is pending and needs to be completed

Done

TODO has been completed

Cancelled

TODO has been cancelled and will not be completed

Implementations

impl TodoStatus

pub const PENDING: &'static str = "pending"

pub const DONE: &'static str = "done"

pub const CANCELLED: &'static str = "cancelled"

pub fn as_str(&self) -> &str

Converts the status to its string representation.

pub fn can_transition_to(self, target: Self) -> bool

Returns whether a transition from self to target is allowed.

pub fn is_reopen_attempt(from: Self, to: Self) -> bool

Returns true when moving a terminal TODO back to pending (reopen).

pub fn is_terminal(self) -> bool

Returns true when the TODO can no longer be worked on.

Trait Implementations

impl Clone for TodoStatus

fn clone(&self) -> TodoStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TodoStatus

impl Debug for TodoStatus

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

Formats the value using the given formatter.

impl Eq for TodoStatus

impl FromStr for TodoStatus

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for TodoStatus

fn eq(&self, other: &TodoStatus) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TodoStatus

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
