Comprehensive statistics about partitions in an MBR.

This structure provides detailed statistical information about the partitions present in an MBR, including counts by type, size information, and bootability status. It’s useful for disk analysis, partition management tools, and system diagnostics.

Fields

Partition Counts

• total_partitions - Total number of valid partitions
• Bootable_partitions - Number of partitions marked as bootable
• Fat_partitions - Number of FAT file system partitions (FAT16, FAT32, etc.)
• Linux_partitions - Number of Linux-type partitions
• Hidden_partitions - Number of hidden partitions
• Extended_partitions - Number of extended partitions
• Unknown_partitions - Number of partitions with unknown/unrecognized types

Size Information

• Total_used_sectors - Total sectors used by all partitions
• Largest_partition_sectors - Size of the largest partition in sectors
• Smallest_partition_sectors - Size of the smallest partition in sectors

Examples

extern crate alloc;
use file_system::{mbr::{Mbr, PartitionKind, PartitionStatistics}, MemoryDevice};

let device = MemoryDevice::<512>::new(4 * 1024 * 1024);
// Create an MBR with some partitions
let mut mbr = Mbr::new_with_signature(0x12345678);
mbr.add_partition(PartitionKind::Fat32Lba, 2048, 1024, true).unwrap();
mbr.add_partition(PartitionKind::Linux, 4096, 2048, false).unwrap();
mbr.write_to_device(&device).unwrap();

// Read it back and get statistics
let mbr = Mbr::read_from_device(&device).unwrap();
let stats = mbr.get_statistics();
println!("Total partitions: {}", stats.total_partitions);
println!("Bootable partitions: {}", stats.bootable_partitions);
println!("Total used sectors: {}", stats.total_used_sectors);
