Struct AllFilter 

pub struct AllFilter { /* private fields */ }

Implementation of RecordFilter that combines multiple filters with AND logic.

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

This filter is useful for combining multiple filtering conditions where all must be satisfied.

Examples

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

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

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

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

Implementations

impl AllFilter

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

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

Arguments

• filters - A vector of boxed filters implementing RecordFilter trait

Examples

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

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

Trait Implementations

impl Debug for AllFilter

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

Formats the value using the given formatter.

impl RecordFilter for AllFilter

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.
