Enum Course 

pub enum Course {
    Pursue,
    Abandon,
    Superseded,
}

What was decided about the line a decision is about.

This used to be a verdict stuck on a commit — promising, dead-end, superseded — and it was never a property of the code. Here it has what it lacked there: a scope saying which line it is about, a reason in the prose, and a place in the DAG under the question it was answering. invalid is not here and will not be: that one really is the code’s, and it stays in the journal.

Variants

Pursue

Carry on this way. The default reading of a line nobody judged, so saying it is only needed to take an abandonment back.

Abandon

Explored and not worth carrying on. Kept, never deleted: a line that did not work is the most reusable thing an investigation produces, and the only thing that stops it being discovered again.

Superseded

Somebody did it better elsewhere. Not wrong, not the way.

Implementations

impl Course

pub fn read(said: &str) -> Option<Self>

pub fn as_str(&self) -> &'static str

Trait Implementations

impl Clone for Course

fn clone(&self) -> Course

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Course

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Course

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Course

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

Formats the value using the given formatter.

impl PartialEq for Course

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
