Enum Outcome 

pub enum Outcome {
    Verified,
    InvalidSource,
    UnsupportedFeature,
    DisallowedAssumptions,
    ResourceLimit,
    InfrastructureFailure,
}

The outcome of a logos-lean-result/1 document, with the contract’s exit code.

Variants

Verified

Every stage passed.

InvalidSource

A real rejection: the source, the export or the proof is wrong.

UnsupportedFeature

Valid input LOGOS does not (yet) carry to a verified result.

DisallowedAssumptions

The result depends on an assumption outside the policy.

ResourceLimit

A declared budget ran out before a decision.

InfrastructureFailure

The environment failed; nothing was decided about the input.

Implementations

impl Outcome

pub const ALL: [Outcome; 6]

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

pub fn exit_code(self) -> i32

The contract’s exit code: 0 verified · 1 invalid source · 2 unsupported feature · 3 disallowed assumptions · 4 resource limit · 5 infrastructure failure.

pub fn of_refusal(code: DiagnosticCode, rejected: bool) -> Outcome

The outcome of a refusal: its code’s outcome, or — for a code without one — the verdict kind’s benchmark meaning (a rejection is invalid source, a decline an unsupported feature).

Trait Implementations

impl Clone for Outcome

fn clone(&self) -> Outcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Outcome

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

Formats the value using the given formatter.

impl Display for Outcome

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

Formats the value using the given formatter.

impl Hash for Outcome

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Outcome

fn cmp(&self, other: &Outcome) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Outcome

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

impl PartialOrd for Outcome

fn partial_cmp(&self, other: &Outcome) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
