Enum Tag

#[non_exhaustive]
pub enum Tag {
    Label(Label),
    Uuid(Uuid),
    PartLabel(Label),
    PartUuid(Uuid),
    Id(Id),
}

A device tag.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Label(Label)

Human readable filesystem identifier.

Uuid(Uuid)

Filesystem universally unique identifier.

PartLabel(Label)

Human readable partition identifier.

PartUuid(Uuid)

Partition universally unique identifier.

Id(Id)

Hardware block device ID as generated by udevd.

Implementations

impl Tag

pub fn name(&self) -> TagName

Returns a Tag’s name.

pub fn value(&self) -> &str

Returns a Tag’s value.

pub fn is_label(&self) -> bool

Returns true if this Tag represents a LABEL.

pub fn is_uuid(&self) -> bool

Returns true if this Tag represents a UUID.

pub fn is_partition_label(&self) -> bool

Returns true if this Tag represents a PARTLABEL.

pub fn is_partition_uuid(&self) -> bool

Returns true if this Tag represents a PARTUUID.

pub fn is_id(&self) -> bool

Returns true if this Tag represents a udev device ID.

Trait Implementations

impl AsRef<Tag> for Tag

fn as_ref(&self) -> &Tag

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Tag

fn clone(&self) -> Tag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tag

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

Formats the value using the given formatter.

impl Display for Tag

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

Formats the value using the given formatter.

impl From<Tag> for MountSource

fn from(share: Tag) -> MountSource

Converts to this type from the input type.

impl From<Tag> for Source

fn from(share: Tag) -> Source

Converts to this type from the input type.

impl FromStr for Tag

type Err = ParserError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl PartialEq for Tag

fn eq(&self, other: &Tag) -> 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.

impl TryFrom<&String> for Tag

type Error = ParserError

The type returned in the event of a conversion error.

fn try_from(s: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for Tag

type Error = ParserError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for Tag

type Error = ParserError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Tag

impl StructuralPartialEq for Tag
