Enum NoMatch

pub enum NoMatch {
    Nothing,
    Ambiguous(Vec<String>),
    TooWeak {
        best: String,
        score: u8,
    },
}

Why nothing was attached, which is worth saying rather than returning None and letting the caller invent a reason.

Variants

Nothing

The search came back with nothing at all.

Ambiguous(Vec<String>)

Several answers are equally good, and choosing between them would be arbitrary. Names are carried for display, with identifiers when names alone cannot distinguish the candidates.

TooWeak

The best answer is not close enough to the name asked about.

Fields

best: String

The best candidate’s name, so the reader can see what was rejected.

score: u8

Its search score.

Trait Implementations

impl Clone for NoMatch

fn clone(&self) -> NoMatch

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NoMatch

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

Formats the value using the given formatter.

impl PartialEq for NoMatch

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