Enum PolicyOutcome 

pub enum PolicyOutcome {
    Allow = 0,
    AllowWithLog = 1,
    Modify = 2,
    Deny = 3,
}

Policy outcome with deterministic precedence.

The precedence order forms a semilattice: Deny > Modify > Allow with Log as a side-effect.

This ensures:

1. Deterministic conflict resolution
2. Associative composition
3. Security-biased defaults (Deny wins)

Variants

Allow = 0

Operation is allowed (lowest precedence)

AllowWithLog = 1

Operation is allowed but logged

Modify = 2

Operation is allowed with modification

Deny = 3

Operation is blocked (highest precedence)

Implementations

impl PolicyOutcome

pub fn join(self, other: PolicyOutcome) -> PolicyOutcome

Combine two outcomes using the semilattice join (max precedence wins)

Trait Implementations

impl Clone for PolicyOutcome

fn clone(&self) -> PolicyOutcome

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyOutcome

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

Formats the value using the given formatter.

impl From<&PolicyAction> for PolicyOutcome

fn from(action: &PolicyAction) -> Self

Converts to this type from the input type.

impl Ord for PolicyOutcome

fn cmp(&self, other: &PolicyOutcome) -> 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 PolicyOutcome

fn eq(&self, other: &PolicyOutcome) -> 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 PolicyOutcome

fn partial_cmp(&self, other: &PolicyOutcome) -> 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.
