Struct FilterSet 

pub struct FilterSet { /* private fields */ }

Compiled filter set. patterns parses the raw Filters: [{Pattern: "..."}] strings into JSON objects once at create time.

Implementations

impl FilterSet

pub fn from_strings<I, S>(raw: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Build from the raw filter pattern strings stored on crate::state::EventSourceMapping::filter_patterns. Patterns that fail to parse are logged and dropped; pre-validation at Self::validate (called from CreateEventSourceMapping) keeps the live data clean.

pub fn validate<I, S>(raw: I) -> Result<(), String>

where I: IntoIterator<Item = S>, S: AsRef<str>,

Validate raw filter patterns the same way real AWS rejects bad FilterCriteria at CreateEventSourceMapping. Returns the first invalid pattern’s parse error so the service can surface it as InvalidParameterValueException.

pub fn matches(&self, record: &Value) -> bool

Returns true when the record matches at least one pattern, or when the filter set is empty (no filtering = pass-through).

pub fn is_empty(&self) -> bool
