1//! A minimal no_std ELF (32/64) parser.
2//!
3//! ## Example Usage
4//! ```ignore
5//! use elf_parser::Elf64;
6//!
7//! fn main() {
8//!     let bytes = include_bytes!("path/to/elf_file");
9//!     let elf64 = Elf64::from_bytes(bytes).unwrap();
10//!     let ehdr = elf64.ehdr();
11//!     dbg!(ehdr);
12//!     
13//!     let phdr_iter = elf64.phdr_iter();
14//!     for phdr in phdr_iter {     
15//!         dbg!(phdr);
16//!     }
17//! }
