Struct GpuDfa 

#[non_exhaustive]
pub struct GpuDfa { /* private fields */ }

A GPU-compiled DFA scanner.

Implementations

impl GpuDfa

pub fn compile( device: &Device, transitions: &[u32], state_count: usize, accept_states: &[(u32, u32)], output_links: &[u32], pattern_lengths: &[u32], ) -> Result<Self>

Internal pipeline helper. User-facing DFA construction lives in std::pattern::aho_corasick_build.

Errors

Returns Error::Dfa when the table, output links, or bindings are invalid.

pub fn compile_with_max_matches( device: &Device, transitions: &[u32], state_count: usize, accept_states: &[(u32, u32)], output_links: &[u32], pattern_lengths: &[u32], max_matches: u32, ) -> Result<Self>

Internal pipeline helper. User-facing DFA construction lives in std::pattern::aho_corasick_build.

Errors

Returns Error::Dfa when validation of the DFA or GPU binding sizes fails.

pub fn scan( &self, device: &Device, queue: &Queue, input: &[u8], command_encoder: Option<&mut CommandEncoder>, ) -> Result<Vec<Match>>

Scan input bytes on the GPU and return captured matches.

Errors

Returns Error::Dfa if the input, device, queue, or readback is invalid.

pub fn scan_shared(&self, input: &[u8]) -> Result<Vec<Match>>

Scan input bytes using the shared vyre device.

Errors

Returns Error::Dfa if this DFA was not compiled on the shared runtime device.

pub fn state_count(&self) -> u32

Number of DFA states in the compiled scanner.

pub fn max_matches(&self) -> u32

Maximum number of matches this scanner captures.

pub fn pattern_lengths(&self) -> &[u32]

Pattern lengths supplied at compile time.

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

Formats the value using the given formatter.
