Struct ShiftOrInterpreter 

pub struct ShiftOrInterpreter<'a> { /* private fields */ }

Interpreter for Shift-Or matching.

This provides the matching logic for the Shift-Or algorithm, operating on a pre-compiled ShiftOr data structure.

Implementations

impl<'a> ShiftOrInterpreter<'a>

pub fn new(shift_or: &'a ShiftOr) -> Self

Creates a new interpreter for the given ShiftOr.

pub fn is_match(&self, input: &[u8]) -> bool

Returns true if the pattern matches anywhere in the input.

pub fn find(&self, input: &[u8]) -> Option<(usize, usize)>

Finds the first match, returning (start, end).

pub fn find_at(&self, input: &[u8], pos: usize) -> Option<(usize, usize)>

Finds a match starting at or after the given position. Returns (start, end) if found.

pub fn try_match_at(&self, input: &[u8], pos: usize) -> Option<(usize, usize)>

Tries to match at exactly the given position. Returns (start, end) if matched, None otherwise. Use this when you know the match should start at exactly pos (e.g., from a prefilter).
