pub struct StreamScanner<'ss> { /* private fields */ }

Implementations

impl<'ss> StreamScanner<'ss>

pub fn close<F>(self, on_match: F) -> Result<Scan, Error>

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

Close the given Stream object using hs_close_stream.

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_stream
• match_event_handler
