Struct CompiledFilter 

pub struct CompiledFilter { /* private fields */ }

A compiled filter ready for evaluation.

This struct contains the bytecode and all pre-compiled resources needed for fast evaluation. Create one at startup and reuse it for all payload evaluations.

Implementations

impl CompiledFilter

pub fn new( bytecode: Vec<u8>, strings: Vec<Vec<u8>>, regexes: Vec<Regex>, string_sets: Vec<Vec<u16>>, delimiter: Vec<u8>, source: String, ) -> Self

Create a new compiled filter from components.

This is typically called by the compiler, not directly.

pub fn evaluate(&self, payload: Bytes) -> bool

Evaluate the filter against a record.

Arguments

• payload - The record payload to evaluate

Returns

true if the filter matches, false otherwise.

Performance

• Zero allocations during evaluation
• SIMD-accelerated string matching
• Fixed-size stack (no heap)

Panics

In debug builds only, panics if the bytecode is malformed (invalid opcode or stack overflow). In release builds, returns false for invalid bytecode.

pub fn source(&self) -> &str

Get the original filter source.

pub fn bytecode_len(&self) -> usize

Get the bytecode length.

pub fn string_count(&self) -> usize

Get the number of string literals.

pub fn regex_count(&self) -> usize

Get the number of regex patterns.

pub fn delimiter(&self) -> &[u8]

Get the delimiter used for splitting.

Trait Implementations

impl Debug for CompiledFilter

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

Formats the value using the given formatter.
