Struct PartitionID

pub struct PartitionID {
    pub variant: PartitionSource,
    pub id: String,
}

Describes a partition identity.

A device path may be recovered from this.

Notes

This is a struct instead of an enum to make access to the id string easier for situations where the variant does not need to be checked.

Fields

variant: PartitionSource

id: String

Implementations

impl PartitionID

pub fn new(variant: PartitionSource, id: String) -> PartitionID

Construct a new PartitionID as the given source.

pub fn new_id(id: String) -> PartitionID

Construct a new PartitionID as a ID source.

pub fn new_label(id: String) -> PartitionID

Construct a new PartitionID as a Label source.

pub fn new_uuid(id: String) -> PartitionID

Construct a new PartitionID as a UUID source.

pub fn new_partlabel(id: String) -> PartitionID

Construct a new PartitionID as a PartLabel source.

pub fn new_partuuid(id: String) -> PartitionID

Construct a new PartitionID as a PartUUID source.

pub fn new_path(id: String) -> PartitionID

Construct a new PartitionID as a Path source.

pub fn get_device_path(&self) -> Option<PathBuf>

Find the device path of this ID.

pub fn get_source<P>(variant: PartitionSource, path: P) -> Option<PartitionID>

where P: AsRef<Path>,

Find the given source ID of the device at the given path.

pub fn get_uuid<P>(path: P) -> Option<PartitionID>

where P: AsRef<Path>,

Find the UUID of the device at the given path.

pub fn get_partuuid<P>(path: P) -> Option<PartitionID>

where P: AsRef<Path>,

Find the PARTUUID of the device at the given path.

pub fn from_disk_by_path<S>(path: S) -> Result<PartitionID, Error>

where S: AsRef<str>,

Fetch a partition ID by a /dev/disk/by- path.

Trait Implementations

impl Clone for PartitionID

fn clone(&self) -> PartitionID

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PartitionID

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for PartitionID

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromStr for PartitionID

type Err = Error

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<PartitionID, <PartitionID as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for PartitionID

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PartitionID

fn eq(&self, other: &PartitionID) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
