Implementations

impl Filter

pub fn new() -> Self

Create a new empty filter

pub fn all(filters: Vec<Filter>) -> Self

Create a filter that matches ALL conditions (AND)

pub fn any(filters: Vec<Filter>) -> Self

Create a filter that matches ANY condition (OR)

pub fn eq<K: Into<String>, V: Into<FilterValue>>(self, key: K, value: V) -> Self

Add equality condition

pub fn ne<K: Into<String>, V: Into<FilterValue>>(self, key: K, value: V) -> Self

Add not-equal condition

pub fn gt<K: Into<String>, V: Into<FilterValue>>(self, key: K, value: V) -> Self

Add greater-than condition

pub fn gte<K: Into<String>, V: Into<FilterValue>>( self, key: K, value: V, ) -> Self

Add greater-than-or-equal condition

pub fn lt<K: Into<String>, V: Into<FilterValue>>(self, key: K, value: V) -> Self

Add less-than condition

pub fn lte<K: Into<String>, V: Into<FilterValue>>( self, key: K, value: V, ) -> Self

Add less-than-or-equal condition

pub fn in_list<K: Into<String>, V: Into<FilterValue>>( self, key: K, values: V, ) -> Self

Add IN condition (value must be in list)

pub fn not_in<K: Into<String>, V: Into<FilterValue>>( self, key: K, values: V, ) -> Self

Add NOT IN condition (value must not be in list)

pub fn contains<K: Into<String>, V: Into<String>>( self, key: K, substring: V, ) -> Self

Add contains condition (string contains substring)

pub fn starts_with<K: Into<String>, V: Into<String>>( self, key: K, prefix: V, ) -> Self

Add starts_with condition

pub fn conditions(&self) -> &[FilterCondition]

Get the conditions

pub fn is_empty(&self) -> bool

Check if filter is empty

pub fn matches(&self, metadata: &Metadata) -> bool

Evaluate filter against metadata
