Enum Flight 

pub enum Flight {
    Idle,
    Flying {
        to: usize,
    },
    Mending,
    Review {
        before: String,
        after: String,
        lines: Vec<Range<usize>>,
        diff: LineDiff,
    },
    Failed(String),
}

Where the fairy is and what the card shows.

Variants

Idle

On her button.

Flying

On her way to line to while the worker thinks.

Fields

to: usize

Mending

At the line, mending.

Review

The mend is back: both texts, and the lines of after it touched (diff has both sides).

Fields

before: String

after: String

lines: Vec<Range<usize>>

diff: LineDiff

Failed(String)

No mend: the reason, in the card’s place.

Implementations

impl Flight

pub fn busy(&self) -> bool

Whether Heal is busy (the button waits).

pub fn begin(text: &str) -> Flight

Heal pressed over text: the flight begins, or the dock says the editor is empty.

pub fn arrived(self) -> Flight

The fairy reached the line.

pub fn answered(before: String, outcome: Result<String, String>) -> Flight

The worker answered: a review of both texts, or the reason there is none. A mend that changed nothing is reported as such rather than reviewed.

pub fn keep(self) -> (Flight, Option<String>)

Keep: the healed text to write into the editor, and the fairy goes home.

pub fn undo(self) -> Flight

Undo (or closing a failure): the editor is untouched, and the fairy goes home.

pub fn line(&self) -> usize

The line the fairy stands at: the first the mend touched, else where she was sent.

Trait Implementations

impl Clone for Flight

fn clone(&self) -> Flight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Flight

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

Formats the value using the given formatter.

impl PartialEq for Flight

fn eq(&self, other: &Flight) -> 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.
