Enum Runnability 

pub enum Runnability {
    Playground,
    CompiledOnly {
        reason: &'static str,
    },
    ExpectedError {
        message: &'static str,
    },
}

How an example behaves in the browser playground. The single source of truth shared by the Run-button affordance, the badge, AND the test harness partition (tests/guide_examples.rs) — the three can never disagree.

Variants

Playground

Executes in the browser playground.

CompiledOnly

The runtime only exists in compiled Rust; the UI renders a badge with the reason instead of a Run button that would fail.

Fields

reason: &'static str

ExpectedError

The example fails ON PURPOSE — the displayed Socratic error is the content. The full diagnostic text is locked exactly.

Fields

message: &'static str

Trait Implementations

impl Clone for Runnability

fn clone(&self) -> Runnability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Runnability

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

Formats the value using the given formatter.

impl PartialEq for Runnability

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