Struct FieldConditionBuilder 

pub struct FieldConditionBuilder<'a, T> { /* private fields */ }

Builder for field-based conditions

Example

use condition_matcher::{FieldConditionBuilder, Matchable, MatchableDerive, RuleMatcher, MatcherMode, Matcher};

#[derive(MatchableDerive, PartialEq)]
struct User {
    age: u32,
}

let condition = FieldConditionBuilder::<User>::new("age").gte(&18u32);

let mut matcher = RuleMatcher::new(MatcherMode::AND);
matcher.add_condition(condition);

let user = User { age: 25 };
assert!(matcher.matches(&user));

Implementations

impl<'a, T: Matchable> FieldConditionBuilder<'a, T>

pub fn new(field: &'a str) -> Self

Create a new field condition builder for the given field

pub fn equals(self, value: &'a dyn Any) -> Condition<'a, T>

Field equals value

pub fn not_equals(self, value: &'a dyn Any) -> Condition<'a, T>

Field not equals value

pub fn gt(self, value: &'a dyn Any) -> Condition<'a, T>

Field greater than value

pub fn gte(self, value: &'a dyn Any) -> Condition<'a, T>

Field greater than or equal value

pub fn lt(self, value: &'a dyn Any) -> Condition<'a, T>

Field less than value

pub fn lte(self, value: &'a dyn Any) -> Condition<'a, T>

Field less than or equal value

pub fn contains(self, value: &'a dyn Any) -> Condition<'a, T>

Field contains substring (for string fields)

pub fn starts_with(self, value: &'a dyn Any) -> Condition<'a, T>

Field starts with prefix (for string fields)

pub fn ends_with(self, value: &'a dyn Any) -> Condition<'a, T>

Field ends with suffix (for string fields)
