<h3 id="unified-read-api"><a href="#unified-read-api">Unified read API</a></h3>
|
||
<p>The <a href="trait.Object.html" title="trait object::read::Object"><code>Object</code></a> trait provides a unified read API for accessing common features of
|
||
object files, such as sections and symbols. There is an implementation of this
|
||
trait for <a href="enum.File.html" title="enum object::read::File"><code>File</code></a>, which allows reading any file format, as well as implementations
|
||
for each file format:
|
||
<a href="elf/struct.ElfFile.html" title="struct object::read::elf::ElfFile"><code>ElfFile</code></a>, <a href="macho/struct.MachOFile.html" title="struct object::read::macho::MachOFile"><code>MachOFile</code></a>, <a href="coff/struct.CoffFile.html" title="struct object::read::coff::CoffFile"><code>CoffFile</code></a>,
|
||
<a href="pe/struct.PeFile.html" title="struct object::read::pe::PeFile"><code>PeFile</code></a>, <a href="wasm::WasmFile"><code>WasmFile</code></a>, <a href="xcoff::XcoffFile"><code>XcoffFile</code></a>.</p>
|
||
<h3 id="low-level-read-api"><a href="#low-level-read-api">Low level read API</a></h3>
|
||
<p>The submodules for each file format define helpers that operate on the raw structs.
|
||
These can be used instead of the unified API, or in conjunction with it to access
|
||
details that are not available via the unified API.</p>
|
||
<p>See the <a href="#modules">submodules</a> for examples of the low level read API.</p>
|
||
<h3 id="naming-convention"><a href="#naming-convention">Naming Convention</a></h3>
|
||
<p>Types that form part of the unified API for a file format are prefixed with the
|
||
name of the file format.</p>
