A trait for generic access to macho::MachHeader32 and macho::MachHeader64.

Required Associated Types

type Word: Into<u64>

type Endian: Endian

type Segment: Segment<Endian = Self::Endian, Section = Self::Section>

type Section: Section<Endian = Self::Endian>

type Nlist: Nlist<Endian = Self::Endian>

Required Methods

fn is_type_64(&self) -> bool

Return true if this type is a 64-bit header.

This is a property of the type, not a value in the header data.

fn is_big_endian(&self) -> bool

Return true if the magic field signifies big-endian.

fn is_little_endian(&self) -> bool

Return true if the magic field signifies little-endian.

fn magic(&self) -> u32

fn cputype(&self, endian: Self::Endian) -> u32

fn cpusubtype(&self, endian: Self::Endian) -> u32

fn filetype(&self, endian: Self::Endian) -> u32

fn ncmds(&self, endian: Self::Endian) -> u32

fn sizeofcmds(&self, endian: Self::Endian) -> u32

fn flags(&self, endian: Self::Endian) -> u32

Provided Methods

fn parse<'data, R: ReadRef<'data>>(data: R, offset: u64) -> Result<&'data Self>

Read the file header.

Also checks that the magic field in the file header is a supported format.

fn is_supported(&self) -> bool

fn endian(&self) -> Result<Self::Endian>

fn load_commands<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, header_offset: u64, ) -> Result<LoadCommandIterator<'data, Self::Endian>>

fn uuid<'data, R: ReadRef<'data>>( &self, endian: Self::Endian, data: R, header_offset: u64, ) -> Result<Option<[u8; 16]>>

Return the UUID from the LC_UUID load command, if one is present.
