Hadris Partition

Partition table support for MBR, GPT, and Hybrid MBR.

Overview

This crate provides read and write support for common partition table formats used in disk images and storage devices.

Features

MBR - Legacy BIOS partition tables (4 primary partitions)
GPT - Modern UEFI partition tables (128+ partitions with GUIDs)
Hybrid MBR - Combined MBR+GPT for dual BIOS/UEFI boot compatibility
No-std Compatible - Use in bootloaders and embedded systems

Feature Flags

Feature	Description	Dependencies	Default
`std`	Standard library support	`alloc`	Yes
`alloc`	Heap allocation for Vec-based APIs	-	-
`read`	Reading partition tables	-	-
`write`	Writing partition tables	`alloc`, `read`	-

Usage

Reading Partition Tables

use hadris_part::{Mbr, Gpt};

// Read MBR
let mbr = Mbr::read(&mut disk)?;
for partition in mbr.partitions() {
    println!("Partition: {} sectors at LBA {}",
             partition.sector_count(),
             partition.start_lba());
}

// Read GPT
let gpt = Gpt::read(&mut disk)?;
for entry in gpt.entries() {
    println!("Partition: {} - {}",
             entry.name(),
             entry.partition_type_guid());
}

For Bootloaders (minimal footprint)

[dependencies]
hadris-part = { version = "0.2", default-features = false, features = ["read"] }

For Desktop Applications

[dependencies]
hadris-part = { version = "0.2", features = ["read", "write"] }

Partition Types

MBR Partition Types

Common partition type IDs:

0x00 - Empty
0x0B - FAT32 (CHS)
0x0C - FAT32 (LBA)
0x0E - FAT16 (LBA)
0x07 - NTFS/exFAT
0x83 - Linux
0xEE - GPT Protective MBR

GPT Partition GUIDs

Common partition type GUIDs:

EFI System Partition: C12A7328-F81F-11D2-BA4B-00A0C93EC93B
Microsoft Basic Data: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7
Linux Filesystem: 0FC63DAF-8483-4772-8E79-3D69D8477DE4
