Struct Sequence 

pub struct Sequence { /* private fields */ }

The automaton for some pieces that have to appear in order.

Implementations

impl Sequence

pub fn new(pieces: &[&[u8]]) -> Option<Self>

The automaton for pieces in this order, or None when there is nothing to find or too much.

Empty pieces are dropped, since finding nothing is always done. With nothing left every string holds the pieces, which is not a question worth a walk, and pieces longer than 254 bytes between them would need more states than a byte counts.

pub fn needs(&self) -> u64

The sketch bits a string has to have to hold the pieces. A string whose grams lack any of them does not hold the pieces, and one that has them all may.

Zero when no piece is three bytes long, which every string passes.

pub fn holds(&self, text: &[u8]) -> bool

Whether text holds the pieces in order.

pub fn over<'a>(&'a self, table: &'a SymbolTable) -> Coded<'a>

A walker over strings compressed against table.
