partition-identity

Find the ID of a device by its path, or find a device path by its ID.

This crate was developed for inclusion in the distinst project.

Example

```rust extern crate partition_identity;

use partition_identity::{PartitionID, PartitionSource}; use self::PartitionSource::*; use std::env; use std::process::exit;

fn main() { let mut args = env::args().skip(1); match args.next() { Some(arg) => match arg.asstr() { "from-path" => { let mut first = true; for device in args { if ! first { println!() } first = false; println!("{}:", device); println!("ID: {:?}", PartitionID::getsource(ID, &device).map(|id| id.id)); println!("Label: {:?}", PartitionID::getsource(Label, &device).map(|id| id.id)); println!("PartLabel: {:?}", PartitionID::getsource(PartLabel, &device).map(|id| id.id)); println!("PartUUID: {:?}", PartitionID::getsource(PartUUID, &device).map(|id| id.id)); println!("Path: {:?}", PartitionID::getsource(Path, &device).map(|id| id.id)); println!("UUID: {:?}", PartitionID::getsource(UUID, &device).map(|id| id.id)); } } "by-uuid" => { for id in args { let var = PartitionID::newuuid(id.clone()); println!("{}: {:?}", id, var.getdevicepath()); } } "by-partuuid" => { for id in args { let var = PartitionID::newpartuuid(id.clone()); println!("{}: {:?}", id, var.getdevice_path()); } } _ => { eprintln!("invalid subcommand: valid commansd: [from-path, by-uuid, by-partuuid, ]"); exit(1); } } None => { eprintln!("must give subcommand: [from-path, by-uuid, by-partuuid, ]"); exit(1); } } } ```
