Struct Symbol32

#[repr(C)]
pub struct Symbol32 {
    pub st_name: Elf32Word,
    pub st_value: Elf32Addr,
    pub st_size: Elf32Word,
    pub st_info: u8,
    pub st_other: u8,
    pub st_shndx: Elf32Section,
    pub symbol_name: String,
}

Symbol32 is a entry of symbol table section.

Symbol32 はシンボルテーブルセクションのエントリである． ELF32で用いることを想定している．

Defaultトレイトを実装しているので， Default::default() を呼び出すことで簡単にNULLシンボルを作成できる．

Examples

use elf_utilities::symbol::Symbol32;
let null_sym : Symbol32 = Default::default();

// Symbol32::new_null_symbol() のエイリアスでも作成可能．
let null_sym2 : Symbol32 = Symbol32::new_null_symbol();

assert_eq!(null_sym, null_sym2);

ELFファイルを生成する用途でこのライブラリを使用できるように， バイト列への変換もサポートしている．

Examples

use elf_utilities::symbol::Symbol32;
let null_sym : Symbol32 = Default::default();

// to_le_bytes() を利用してバイト列に変換できる．
let sym_bytes = null_sym.to_le_bytes();
assert_eq!(Symbol32::SIZE as usize, sym_bytes.len())

Fields

st_name: Elf32Word

Symbol name index.

st_value: Elf32Addr

Symbol’s value.

st_size: Elf32Word

Symbol’s size.

st_info: u8

Information that includes symbol binds and symbol types.

st_other: u8

Symbol’s visibility. See symbol::VISIBILITY.

st_shndx: Elf32Section

A section table index that includes the symbol.

symbol_name: String

option member for utilities.

Implementations

impl Symbol32

pub const SIZE: usize = 16usize

SIZE provides Symbol32’s size used by Shdr32.sh_entsize or else.

pub fn new_null_symbol() -> Self

pub fn compare_by<P>(&self, predicate: P) -> bool

where P: Fn(&Self) -> bool,

for utilities

pub fn get_type(&self) -> Type

pub fn get_bind(&self) -> Bind

pub fn get_visibility(&self) -> Visibility

pub fn set_info(&mut self, sym_type: Type, bind: Bind)

Set symbol’s information to Symbol32

Examples

use elf_utilities::symbol;
let mut null_sym = symbol::Symbol32::new_null_symbol();

null_sym.set_info(symbol::Type::Func, symbol::Bind::Global);

assert_eq!((1 << 4) | 2, null_sym.st_info);

pub fn to_le_bytes(&self) -> Vec<u8>

Create Vec from Symbol32’s each fields.

Examples

use elf_utilities::symbol::Symbol32;
let null_sym : Symbol32 = Default::default();

assert_eq!([0].repeat(Symbol32::SIZE as usize), null_sym.to_le_bytes());

pub fn deserialize(buf: &[u8], start: usize) -> Result<Self, Box<dyn Error>>

Trait Implementations

impl Clone for Symbol32

fn clone(&self) -> Symbol32

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Symbol32

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

Formats the value using the given formatter.

impl Default for Symbol32

fn default() -> Symbol32

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Symbol32

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Symbol32

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 Symbol32

fn cmp(&self, other: &Symbol32) -> 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 Symbol32

fn eq(&self, other: &Symbol32) -> 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 Symbol32

fn partial_cmp(&self, other: &Symbol32) -> 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.

impl Serialize for Symbol32

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
