Struct BlockScanner 

pub struct BlockScanner<'db> { /* private fields */ }

A scanner that supports Vectorscan’s block-based matching APIs

Implementations

impl<'db> BlockScanner<'db>

pub fn new(db: &'db BlockDatabase) -> Result<Self, Error>

Create a new scanner with the given database

pub fn scan<F>(&mut self, data: &[u8], on_match: F) -> Result<Scan, Error>

where F: FnMut(u32, u64, u64, u32) -> Scan,

Scan the input using the given callback function

The callback function takes 4 arguments and returns a Scan value. The 4 arguments:

• id: u32 The ID of the expression that matched
• from: u64 The offset of the start byte of the match; in practice, always 0
• to: u64 The offset of the byte after the end byte of the match
• flags: u32 Unused; “provided for future use”

For more detail, see the Hyperscan documentation:

• hs_scan
• match_event_handler
