Enum FlowPredicate 

pub enum FlowPredicate {
    TargetRolePrefix(String),
    FactContains(String),
    EndpointRoleMatchesTarget,
    All(Vec<FlowPredicate>),
    Any(Vec<FlowPredicate>),
}

Serializable flow-policy predicate over known fact + destination.

Variants

TargetRolePrefix(String)

Allow when destination role starts with prefix.

FactContains(String)

Allow when fact contains substring.

EndpointRoleMatchesTarget

Allow when the fact endpoint role equals destination role.

All(Vec<FlowPredicate>)

Conjunction.

Any(Vec<FlowPredicate>)

Disjunction.

Implementations

impl FlowPredicate

pub fn eval(&self, knowledge: &KnowledgeFact, target_role: &str) -> bool

Evaluate this serialized predicate against one fact and target role.

Trait Implementations

impl Clone for FlowPredicate

fn clone(&self) -> FlowPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowPredicate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FlowPredicate

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FlowPredicate

fn eq(&self, other: &FlowPredicate) -> 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 Serialize for FlowPredicate

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
