Enum DischargeOutcome 

pub enum DischargeOutcome {
    Proved,
    Refuted {
        reason: String,
    },
    Deferred {
        reason: String,
    },
}

Variants

Proved

Predicate evaluated to true with the binding bound to the argument value. Static check succeeds; no runtime work.

Refuted

Predicate evaluated to false. The call-site argument definitely violates the refinement — surface as a type error.

Fields

reason: String

Deferred

Couldn’t decide statically. Slice 3 will emit a residual runtime check at the call boundary; this slice just lets type-check pass.

Fields

reason: String

Trait Implementations

impl Clone for DischargeOutcome

fn clone(&self) -> DischargeOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DischargeOutcome

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

Formats the value using the given formatter.

impl PartialEq for DischargeOutcome

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