Enum FilterResult 

#[non_exhaustive]
pub enum FilterResult {
    NoMatch,
    Match,
    MatchWithData(HashMap<String, Vec<String>>),
}

Result of a filter check, supporting data filters (like Python’s data_filter).

Simple filters return Match or NoMatch. Data filters (e.g. regex) return MatchWithData carrying named capture groups or other extracted data.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NoMatch

The filter did not match.

Match

The filter matched but produced no additional data.

MatchWithData(HashMap<String, Vec<String>>)

The filter matched and produced named capture data (e.g. regex groups).

Implementations

impl FilterResult

pub fn is_match(&self) -> bool

Returns true when the filter matched (either Match or MatchWithData).

pub fn merge(self, other: FilterResult) -> FilterResult

Merge data from two FilterResult values. Used by [AndFilter].

• If either side is NoMatch, the result is NoMatch.
• If both carry data, their maps are merged (values appended).
• If only one carries data, that data is preserved.

Trait Implementations

impl Clone for FilterResult

fn clone(&self) -> FilterResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FilterResult

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

Formats the value using the given formatter.

impl PartialEq for FilterResult

fn eq(&self, other: &FilterResult) -> 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.
