Implementations

impl CompiledPack

pub fn open( path: &Path, expected_source_digest: Option<[u8; 32]>, expected_compiled_digest: Option<[u8; 32]>, ) -> Result<Self, String>

Open and verify a compiled pack header and program index.

Errors

Returns an error for an unsafe path, incompatible format, corrupt index, or digest mismatch.

pub fn candidate_indices(&self, program: &str) -> &[u32]

pub fn read_rule(&mut self, index: u32) -> Result<Rule, String>

Read and validate one indexed rule record.

Errors

Returns an error when the index is invalid or the selected record is corrupt or invalid.

pub fn verify_compiled_digest(&mut self) -> Result<(), String>

Rehash the open file and require the bytes to match those observed before parsing.

Errors

Returns an error when the file changed after it was opened.

pub fn verify_all(&mut self) -> Result<(), String>

Verify every record and every program-to-rule reference in the pack.

Errors

Returns an error when any record or index relationship is invalid.

pub const fn records_len(&self) -> u64

Trait Implementations

impl Debug for CompiledPack

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