Struct Label 

pub struct Label(/* private fields */);

A label for an element.

Implementations

impl Label

pub fn new(name: PicoStr) -> Option<Self>

Creates a label from an interned string.

Returns None if the given string is empty.

pub fn resolve(self) -> ResolvedPicoStr

Resolves the label to a string.

pub fn into_inner(self) -> PicoStr

Turns this label into its inner interned string.

impl Label

pub fn construct(name: Str) -> StrResult<Label>

Creates a label from a string.

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Label

impl Debug for Label

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

Formats the value using the given formatter.

impl Eq for Label

impl From<Label> for PicoStr

fn from(value: Label) -> Self

Converts to this type from the input type.

impl FromValue for Label

fn from_value(value: Value) -> HintedStrResult<Self>

Try to cast the value into an instance of Self.

impl Hash for Label

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 IntoValue for Label

fn into_value(self) -> Value

Cast this type into a value.

impl NativeScope for Label

fn constructor() -> Option<&'static NativeFuncData>

The constructor function for the type, if any.

fn scope() -> Scope

Get the associated scope for the type.

impl NativeType for Label

const NAME: &'static str = "label"

The type’s name.

fn data() -> &'static NativeTypeData

fn ty() -> Type

Get the type for the native Rust type.

impl PartialEq for Label

fn eq(&self, other: &Label) -> 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 Reflect for Label

fn input() -> CastInfo

Describe what can be cast into this value.

fn output() -> CastInfo

Describe what this value can be cast into.

fn castable(value: &Value) -> bool

Whether the given value can be converted to T.

fn error(found: &Value) -> HintedString

Produce an error message for an unacceptable value type.

impl Repr for Label

fn repr(&self) -> EcoString

Return the debug representation of the value.
