Struct SectionId 

pub struct SectionId(/* private fields */);

The identity of a section within its Object: its position in Object::sections.

Ids are dense, starting at zero in the order sections were added, so they index straight into the section list. An id is only meaningful for the object that issued it.

Examples

use object_lang::{Architecture, Object, Section, SectionKind};

let mut obj = Object::relocatable(Architecture::X86_64);
let text = obj.add_section(Section::new(".text", SectionKind::Text));
let data = obj.add_section(Section::new(".data", SectionKind::Data));
assert_eq!((text.index(), data.index()), (0, 1));

Implementations

impl SectionId

pub const fn new(index: u32) -> Self

The id of the section at position index in Object::sections.

An id is only an index: one that names no section of the object it is used with is caught by Object::validate (or refused by Object::section), never trusted.

Examples

use object_lang::{Architecture, Object, Section, SectionId, SectionKind};

let mut obj = Object::relocatable(Architecture::X86_64);
let text = obj.add_section(Section::new(".text", SectionKind::Text));
assert_eq!(SectionId::new(0), text);
assert!(obj.section(SectionId::new(1)).is_none());

pub const fn index(self) -> usize

The position of the section in Object::sections.

Examples

use object_lang::{Architecture, Object, Section, SectionKind};

let mut obj = Object::relocatable(Architecture::Aarch64);
let id = obj.add_section(Section::new(".text", SectionKind::Text));
assert_eq!(obj.sections()[id.index()].name(), ".text");
