Implementations

impl InstanceTarget

pub fn or(self, other: InstanceTarget) -> InstanceTarget

Returns self unless self is InstanceTarget::Default, in which case it returns other.

pub fn id(&self) -> Option<&str>

Get the id of the instance target.

pub fn named<T: Into<String>>(name: T) -> Self

Create a new InstanceTarget::Named from a string.

Trait Implementations

impl Clone for InstanceTarget

fn clone(&self) -> InstanceTarget

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstanceTarget

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

Formats the value using the given formatter.

impl Display for InstanceTarget

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

Formats the value using the given formatter.

impl FromStr for InstanceTarget

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 Hash for InstanceTarget

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

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<InstanceTarget> for InstanceTarget

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for InstanceTarget

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.
