Implementations

impl KolyTrailer

pub fn read_from<R: Read + Seek>( reader: &mut R, ) -> Result<Self, AppleCodesignError>

Construct an instance by reading from a seekable reader.

The trailer is the final 512 bytes of the seekable stream.

pub fn offset_after_plist(&self) -> u64

Obtain the offset byte after the plist data.

This is the offset at which an embedded signature superblob would be present. If no embedded signature is present, this is likely the start of KolyTrailer.

pub fn digest_for_code_directory( &self, digest: DigestType, ) -> Result<Vec<u8>, AppleCodesignError>

Obtain the digest of the trailer in a way compatible with code directory digesting.

This will compute the digest of the current values but with the code signature size set to 0.

Trait Implementations

impl Clone for KolyTrailer

fn clone(&self) -> KolyTrailer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for KolyTrailer

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

Formats the value using the given formatter.

impl PartialEq for KolyTrailer

fn eq(&self, other: &KolyTrailer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SizeWith<Endian> for KolyTrailer
