Struct AnyFilter 

pub struct AnyFilter { /* private fields */ }

Implementation of RecordFilter that combines multiple filters with OR logic.

This implementation of the RecordFilter trait accepts a vector of boxed filters during construction. Its check method returns true if any of the underlying filters returns true for the given record. If the filter list is empty, it returns false by default (empty disjunction is false).

This filter is useful for combining multiple filtering conditions where at least one must be satisfied.

Examples

use logged_stream::{AnyFilter, RecordKindFilter, RecordFilter, Record, RecordKind};

// Create a filter that accepts Read OR Write operations
let filter = AnyFilter::new(vec![
    Box::new(RecordKindFilter::new(&[RecordKind::Read])),
    Box::new(RecordKindFilter::new(&[RecordKind::Write])),
]);

let read_record = Record::new(RecordKind::Read, String::from("data"));
assert!(filter.check(&read_record));

let write_record = Record::new(RecordKind::Write, String::from("data"));
assert!(filter.check(&write_record));

let error_record = Record::new(RecordKind::Error, String::from("error"));
assert!(!filter.check(&error_record));

Implementations

impl AnyFilter

pub fn new(filters: Vec<Box<dyn RecordFilter>>) -> Self

Construct a new instance of AnyFilter using provided vector of boxed filters.

Arguments

• filters - A vector of boxed filters implementing RecordFilter trait

Examples

use logged_stream::{AnyFilter, RecordKindFilter, RecordKind};

let filter = AnyFilter::new(vec![
    Box::new(RecordKindFilter::new(&[RecordKind::Read])),
    Box::new(RecordKindFilter::new(&[RecordKind::Write])),
]);

Trait Implementations

impl Debug for AnyFilter

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

Formats the value using the given formatter.

impl RecordFilter for AnyFilter

fn check(&self, record: &Record) -> bool

This method returns bool value depending on if received log record (Record) should be processed by logging part inside LoggedStream.

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

This method provides fmt::Debug representation of the filter. It is used by composite filters (AllFilter and AnyFilter) to produce detailed debug output of their underlying filters. The default implementation outputs the type name as "UnknownFilter". Implementors are encouraged to override this method to provide meaningful debug information.
