Struct Condition 

pub struct Condition {
    pub field: String,
    pub op: CompareOp,
    pub value: Value,
    pub description: Option<String>,
}

A single condition to evaluate

Fields

field: String

Field path to evaluate (dot notation, e.g., “metrics.cpu_usage”)

op: CompareOp

Comparison operator

value: Value

Value to compare against

description: Option<String>

Optional description

Implementations

impl Condition

pub fn new(field: impl Into<String>, op: CompareOp, value: Value) -> Self

Create a new condition

pub fn with_description(self, desc: impl Into<String>) -> Self

Add description

pub fn evaluate(&self, context: &RuleContext) -> bool

Evaluate condition against context

pub fn eq(field: impl Into<String>, value: impl Into<Value>) -> Self

Field equals value

pub fn ne(field: impl Into<String>, value: impl Into<Value>) -> Self

Field not equals value

pub fn gt(field: impl Into<String>, value: impl Into<Value>) -> Self

Field greater than value

pub fn ge(field: impl Into<String>, value: impl Into<Value>) -> Self

Field greater than or equal to value

pub fn lt(field: impl Into<String>, value: impl Into<Value>) -> Self

Field less than value

pub fn le(field: impl Into<String>, value: impl Into<Value>) -> Self

Field less than or equal to value

pub fn contains(field: impl Into<String>, value: impl Into<Value>) -> Self

Field contains value

pub fn is_in(field: impl Into<String>, values: Vec<Value>) -> Self

Field is in set of values

pub fn exists(field: impl Into<String>) -> Self

Field exists

Trait Implementations

impl Clone for Condition

fn clone(&self) -> Condition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Condition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Condition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Condition

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
