Enum ConditionResult 

pub enum ConditionResult {
    True,
    False,
    Unknown,
}

Three-valued result of evaluating a single condition.

Unlike the C# implementation which uses bool, we use three-valued logic to support partial evaluation when external conditions are unavailable.

Variants

True

The condition is satisfied.

False

The condition is not satisfied.

Unknown

The condition cannot be determined (e.g., external condition without a provider).

Implementations

impl ConditionResult

pub fn is_true(self) -> bool

Returns true if this is ConditionResult::True.

pub fn is_false(self) -> bool

Returns true if this is ConditionResult::False.

pub fn is_unknown(self) -> bool

Returns true if this is ConditionResult::Unknown.

pub fn to_option(self) -> Option<bool>

Converts to Option<bool>: True -> Some(true), False -> Some(false), Unknown -> None.

Trait Implementations

impl Clone for ConditionResult

fn clone(&self) -> ConditionResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionResult

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

Formats the value using the given formatter.

impl Display for ConditionResult

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

Formats the value using the given formatter.

impl From<bool> for ConditionResult

fn from(value: bool) -> Self

Converts to this type from the input type.

impl Hash for ConditionResult

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 PartialEq for ConditionResult

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