Enum dsntk_model::HitPolicy

pub enum HitPolicy {
    Unique,
    Any,
    Priority,
    First,
    Collect(BuiltinAggregator),
    OutputOrder,
    RuleOrder,
}

Hit policy.

Variants

Unique

UNIQUE hit policy. No overlapping rules are allowed, only single rule can be matched. This is the default value for hit policy. Crosstab decision tables may have only unique hit policy.

Any

ANY hit policy. Rules may overlap, but all matching rules show equal output entries. If matching rules have non-equal output entries, this policy is incorrect and the result is undefined.

Priority

PRIORITY hit policy. Multiple rules can match, with different output entries for each output. This policy returns matching rule with the highest priority. Output priorities are specified in the ordered list of output values, in decreasing order of priority.

First

FIRST hit policy…

Collect(BuiltinAggregator)

COLLECT hit policy…

OutputOrder

OUTPUT ORDER hit policy…

RuleOrder

RULE ORDER hit policy…

Trait Implementations

impl Clone for HitPolicy

fn clone(&self) -> HitPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HitPolicy

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

Formats the value using the given formatter.

impl Display for HitPolicy

Implementation of Display for HitPolicy.

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

Formats the value using the given formatter.

impl PartialEq for HitPolicy

fn eq(&self, other: &HitPolicy) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&str> for HitPolicy

fn try_from(value: &str) -> Result<Self, Self::Error>

Creates a hit policy from text.

type Error = DsntkError

The type returned in the event of a conversion error.
