Struct Ident

pub struct Ident {
    pub class: Class,
    pub byte_order: ByteOrder,
    pub abi: ABI,
    pub abi_version: u8,
}

e_ident. Specifies class, byte order and ABI of the ELF

Fields

class: Class

Class, ELF32/ELF64

byte_order: ByteOrder

Byte order

abi: ABI

Identifies the target operating system ABI

abi_version: u8

ABI version, usually 0

Implementations

impl Ident

pub fn new( class: Class, byte_order: impl Into<ByteOrder>, abi: impl Into<ABI>, abi_version: u8, ) -> Self

Constructs a new Ident to write it afterwards

pub fn write<W: Write>(&self, file: &mut W) -> Result<()>

Write the Ident to a file. It’s done automatically by the ELF::write()

pub fn read<R: Read>(file: &mut R) -> Result<Self>

Read the Ident from a file. It’s done automatically by the ELF::read(). Can be used with ELF::read_remainder() to determine ELF class:

use orecc_elf::{ELF, Ident, Class};

let mut file = std::fs::File::open("test.o").unwrap();
let ident = Ident::read(&mut file).unwrap();
if ident.class == Class::ELF64 {
    dbg!(ELF::<u64>::read_remainder(&mut file, ident)).unwrap();
} else {
    dbg!(ELF::<u32>::read_remainder(&mut file, ident)).unwrap();
}

Trait Implementations

impl Clone for Ident

fn clone(&self) -> Ident

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ident

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

Formats the value using the given formatter.

impl Default for Ident

fn default() -> Ident

Returns the “default value” for a type.

impl Hash for Ident

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Ident

fn cmp(&self, other: &Ident) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Ident

fn eq(&self, other: &Ident) -> 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 PartialOrd for Ident

fn partial_cmp(&self, other: &Ident) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
